[0003] Case Analysis

[0004] This application is a divisional application of Chinese application filed on September 29, 2018, with application number 201880002473.1 and entitled "System and method for loading and displaying a site". Technical Field

[0005] This application relates to the field of map technology, and more particularly to systems and methods for site loading and display. Background Technology

[0006] With the development of online-to-offline service technologies, stations and specific travel routes (e.g., bus and / or subway lines) are loaded and displayed on digital maps provided by map applications installed on electronic devices. Buses and / or subways in motion can be displayed on specific tracks within the map. The information and data associated with all stations in a city's public transportation system can be vast. When a user travels through an area of ​​the city, more useful information is obtained from nearby stations than from more distant ones. Therefore, it is not necessary to load all stations in the city into the digital map after the user launches the map application. When a user drags the map on the screen of an electronic device, the display area on the user interface may change, and stations in the new display area may not be effectively loaded and displayed, which reduces user satisfaction with the map application.

[0007] Furthermore, there may be two or more stations associated with a specific location, such as the uplink station and the downlink station, which may be located on different sides of the road but not too far apart. When these stations are displayed on a map application, the different stations may overlap because the display area is limited and the display scale is relatively high. In particular, the uplink station and the downlink station are more likely to overlap because they are closer to each other, resulting in unclear and confusing elements on the map (e.g., icons representing stations). Therefore, there is a need to provide systems and methods for improving the user experience of map applications. Summary of the Invention

[0095] For ease of understanding, only one CPU and / or processor is illustrated in the computing device 200. However, it should be noted that the computing device 200 in this application may include multiple CPUs and / or processors, and therefore the operations and / or methods described in this application implemented by one CPU and / or processor may also be implemented jointly or independently by multiple CPUs and / or processors.

[0097] Figure 4This is a block diagram of an exemplary processing engine 112 according to some embodiments of this application. The processing engine 112 may include an acquisition module 410 and a display module 420. Each of the above modules may be designed, for example, as hardware circuitry that performs certain operations according to a set of instructions stored in one or more storage media and / or a combination of hardware circuitry and one or more storage media.

[0098] The acquisition module 410 can be used to acquire a scale associated with a map display area. As used herein, a scale associated with a map display area can represent the relationship between ground distance (also known as actual distance) and the corresponding distance on the map (also known as map distance). In some embodiments, the scale associated with a map display area can be equal to the ratio of actual distance to map distance. In some embodiments, the acquisition module 410 can acquire the scale associated with a map display area from a client (e.g., service requester terminal 130, service provider terminal 140) via network 120. For example, a user associated with the client can input the scale associated with the map display area via a user interface implemented on the client. As another example, a user can zoom in or out of the display area via the user interface, and the acquisition module 410 can determine the scale associated with the map display area based on the user's actions.

[0099] Display module 420 may determine whether to display one or more stations on the map display area based on a scale associated with the map display area. In some embodiments, the one or more stations may include at least one of the uplink stations and / or the downlink stations. Furthermore, display module 420 may determine whether to display the uplink stations and / or the downlink stations within the display area on the map. As used herein, an uplink station may refer to a station on a journey from the origin to the destination. A downlink station may refer to a station on another journey from the destination to the origin. Depending on the scale associated with the map display area, display module 420 may display both the uplink and downlink stations on the map display area, display either the uplink station or the downlink station on the map display area, or display neither the uplink nor the downlink station on the map display area. In some embodiments, display module 420 may display either the uplink station or the downlink station on the map display area based on user settings.

[0100] It should be noted that the above description of the processing engine 112 is provided for illustrative purposes and is not intended to limit the scope of this application. For those skilled in the art, various modifications and alterations can be made to the form and details of the application of the above methods and systems without departing from the principles of this application. However, such modifications and alterations also fall within the scope of this application. In some embodiments, the processing engine 112 may include one or more other modules. For example, the processing engine 112 may include a storage module for storing data generated by the modules in the processing engine 112. In some embodiments, any two modules may be combined into one module, and any module may be divided into two or more units.

[0101] Figure 5 This is a flowchart illustrating an exemplary process for displaying a site, according to some embodiments of this application. In some embodiments, process 500 may be implemented as a set of instructions (e.g., an application program) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112 and / or Figure 4 The module in the document can be configured to execute process 500. The operation of the process presented below is intended to illustrate the concept. In some embodiments, process 500 may be accomplished by one or more additional operations not described herein, and / or by one or more operations not described herein. Additionally, as... Figure 5 The order of operations shown and described below is not restrictive.

[0102] In 510, the processing engine 112 can obtain the scale associated with the map display area.

[0103] As used herein, the scale associated with a map display area can represent the relationship between ground distance (also known as actual distance) and the corresponding distance on the map (also known as map distance). In some embodiments, the scale associated with a map display area can be equal to the ratio of actual distance to map distance. In some embodiments, processing engine 112 can obtain the scale associated with the map display area from a client (e.g., service requester terminal 130, service provider terminal 140) via network 120. For example, a user associated with the client can input the scale associated with the map display area via a user interface implemented on the client. As another example, a user can zoom in or out of the display area via the user interface, and processing engine 112 can determine the scale associated with the map display area based on the user's actions.

[0104] In 520, the processing engine 112 can determine whether to display one or more sites on the map display area based on the scale associated with the map display area.

[0105] In some embodiments, when a user launches a map application from an electronic device, processing engine 112 can locate the user's current location and request access to a site interface (e.g., a site database) to obtain multiple sites within a predetermined range centered on the user's current location. For example, processing engine 112 can obtain multiple sites within 1 kilometer centered on the user's current location. Processing engine 112 can further determine whether to display at least a portion of the multiple sites based on a scale associated with the map display area. Processing engine 112 can display at least a portion of the multiple sites when the user needs them and hide at least a portion of the multiple sites when the user does not need them, which can satisfy the user's need to view one or more sites. Based on the scale associated with the map display area, multiple sites can be displayed on a map by a map application implemented in an electronic device, which can also avoid multiple sites overlapping on the map. Furthermore, it can avoid confusion of elements on the map and visual interference between multiple sites displayed on the map caused by overlapping sites.

[0106] In some embodiments, one or more stations may include at least one of the uplink stations and / or the downlink stations. Furthermore, the processing engine 112 may determine whether to display uplink stations and / or downlink stations located within the map display area on the map based on a scale associated with the map display area. For example, the processing engine 112 may determine to display at least one of an uplink station or a downlink station on the map display area. As another example, the processing engine 112 may determine not to display either an uplink station or a downlink station on the map display area. As used herein, an uplink station may refer to a station on a journey route from the origin to the destination. A downlink station may refer to a station on another journey route from the destination to the origin.

[0107] Depending on the scale associated with the map display area, the processing engine 112 can display both upstream and downstream stations, display only one upstream station or one downstream station, or display neither upstream nor downstream stations on the map display area. Furthermore, the processing engine 112 can determine whether to display upstream or downstream stations based on user settings. For example, if the user's associated route is from origin to destination, the processing engine 112 can determine to display upstream stations on the map display area. If the user's associated route is from destination to origin, the processing engine 112 can determine to display downstream stations on the map display area. In this way, when the user needs it, all stations within a predetermined range centered on the user's current location can be displayed, and when the user does not need it, all or part of the stations within the predetermined range centered on the user's current location can be hidden. Displaying one or more stations on the map based on the scale associated with the map display area avoids dense station coverage of map information when multiple stations are displayed on the map and the scale associated with the map display area is relatively high. For a detailed description, please refer to [link to relevant documentation]. Figure 6-7 And its description.

[0108] It should be noted that the foregoing is provided for illustrative purposes only and is not intended to limit the scope of this application. Various changes and modifications can be made by those skilled in the art based on the teachings of this application. However, these changes and modifications will not depart from the scope of this application. In some embodiments, process 500 may further include displaying one or more stations based on the determination in operation 520. For example, processing engine 112 may display uplink and / or downlink stations within a display area on a map based on a scale associated with the map display area.

[0109] Figure 6 This is a flowchart of another exemplary process for displaying a site according to some embodiments of this application. In some embodiments, process 600 may be implemented as a set of instructions (e.g., an application) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112, and / or modules are... Figure 4 The process 600 can be configured to execute. The operation of the process presented below is intended to illustrate the purpose. In some embodiments, process 600 may be accomplished by one or more additional operations not described, and / or by one or more operations not described herein. Additionally, as Figure 6 The order of operations shown and described below is not restrictive.

[0110] In 610, processing engine 112 can receive operation instructions for zooming the map and obtain the scale associated with the zoomed map display area. In some embodiments, processing engine 112 can obtain the scale associated with the display area from a client (e.g., service requester terminal 130, service provider terminal 140) via network 120, such as in combination with Figure 5 The operation 510 shown is described below. In some embodiments, if the scale associated with the scaled map display area is equal to 10, then 1 cm of map distance equals 10 meters of actual distance. If the scale associated with the scaled map display area is equal to 100, then 1 cm of map distance equals 100 meters of actual distance. It should be noted that the unit of actual distance is meters, and the unit of map distance is centimeters. In some embodiments, the units of actual distance and map distance can be unified, and the values ​​of the first threshold and the second threshold can be changed accordingly.

[0111] In step 620, processing engine 112 can compare the scale associated with the scaled map display area with a first threshold and a second threshold. In some embodiments, the first threshold may be 10 and the second threshold may be 100. By determining whether to show or hide stations on the map display area, different display modes of stations at different scales associated with the map display area, as described in conjunction with operations 630 or 730, can be implemented.

[0112] In step 630, in response to determining that the scale associated with the map display area is less than or equal to a first threshold, uplink and downlink stations are displayed on the map display area. In response to determining that the scale associated with the scaled map display area is greater than the first threshold and less than or equal to a second threshold, processing engine 112 may display either uplink or downlink stations on the map. In response to determining that the scale associated with the scaled map display area is greater than the second threshold, processing engine 112 may display neither uplink nor downlink stations on the map.

[0113] Figure 7 This is a flowchart illustrating another exemplary process for displaying a site, according to some embodiments of this application. In some embodiments, process 700 may be implemented as a set of instructions (e.g., an application) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112, and / or modules are... Figure 4The process 700 can be configured to execute procedure 700. The operation of the procedure presented below is intended to illustrate the purpose. In some embodiments, procedure 700 may be accomplished by one or more additional operations not described herein, and / or by one or more operations not described herein. Additionally, as... Figure 7 The order of operations shown and described below is not restrictive.

[0114] In 710, processing engine 112 can receive operation instructions for zooming the map and obtain the scale associated with the zoomed map display area. In some embodiments, processing engine 112 can obtain the scale associated with the display area from a client (e.g., service requester terminal 130, service provider terminal 140) via network 120, such as in combination with Figure 5 The operation 510 shown in the figure is described.

[0115] In 720, the processing engine 112 can compare the scale associated with the scaled map display area with a first threshold and a second threshold.

[0116] In step 730, in response to determining that the proportion associated with the scale map display area is less than a first threshold, processing engine 112 may display both uplink and downlink stations on the map. In response to determining that the proportion associated with the scale map display area is greater than or equal to the first threshold and less than a second threshold, processing engine 112 may display either uplink or downlink stations on the map. In response to determining that the proportion associated with the scale map display area is greater than or equal to the second threshold, processing engine 112 may display neither uplink nor downlink stations on the map.

[0117] In some embodiments, the scale associated with the map display area can change after the user zooms in on the map. Based on the change in scale associated with the map display area caused by the user zooming in, the processing engine 112 can determine whether to display uplink and / or downlink stations, or neither, to facilitate the user viewing one or more stations. The processing engine 112 can determine the range to which the changed scale associated with the zoomed map display area belongs. Furthermore, the processing engine 112 can determine whether to display uplink and / or downlink stations based on the range to which the changed scale associated with the zoomed map display area belongs. The processing engine 112 can determine whether to display one or more stations when needed or hide one or more stations when not needed by comparing the changed scale associated with the zoomed map display area to at least one threshold (e.g., a first threshold, a second threshold, etc.). In this way, the system 100 can ensure the user's needs are met while avoiding station overlap on the map.

[0118] In some embodiments, the first threshold may be 10, and the second threshold may be 100.

[0119] In some embodiments, if the scale associated with the scaled map display area is 10, then 1 centimeter of map distance equals 10 meters of actual distance. If the scale associated with the scaled map display area is 100, then 1 centimeter of map distance equals 100 meters of actual distance. It should be noted that the unit of actual distance is meters, while the unit of map distance is centimeters. In some embodiments, the units of actual distance and map distance may be unified, and the values ​​of actual distance or map distance may be changed accordingly.

[0120] Figure 8A This is a block diagram of another exemplary processing engine 112 according to some embodiments of this application. Processing engine 112 may include a location acquisition module 802, a loading display module 804, a receiving module 806, a calculation module 808, and a judgment module 810. Each of the above modules may be designed, for example, as hardware circuitry that performs certain operations according to a set of instructions stored in one or more storage media and / or a combination of hardware circuitry and one or more storage media.

[0121] Location acquisition module 802 can acquire the user's current location. Location acquisition module 802 can designate the user's current location as the first center location of the map. As used herein, the user's current location can be the user's geographic location. The user's geographic location can be associated with and obtained from a client carried by the user. For example, processing engine 112 can acquire the user's geographic location based on the client's location information determined by the client's positioning chipset. Alternatively, the user's geographic location can be input by the user through the client's user interface (e.g., a map application). The center location of the map can refer to the location on the map corresponding to the geometric center of the map display area.

[0122] When the map display area changes, the location acquisition module 802 can also be used to acquire a second center position of the map. In some embodiments, the map display area can change when the user drags the map. In response to an operation command from a user-carried client to drag the map, the location acquisition module 802 can determine the changed map display area. The location acquisition module 802 can designate the center position of the changed map display area as the second center position.

[0123] The loading display module 804 can be configured to load a plurality of first stations within a first preset distance from a first center location. Then, the loading display module 804 can display a first group of stations on the map display area. The first group of stations may include at least a portion of the plurality of first stations within the map display area. If the distance between the first center location and the second center location exceeds a second preset distance, the loading display module 804 can load a plurality of second stations located within a first preset distance from a second center location of the changed map display area. Then, the loading display module 804 can display a second group of stations on the changed map display area. The second group of stations may include at least a portion of the plurality of first stations and at least a portion of the plurality of second stations within the changed map display area. If the distance between the first center location and the second center location is less than or equal to the second preset distance, the display module 804 can display a third group of stations on the changed map display area. The third group of stations may include at least a portion of the plurality of first stations within the changed map display area.

[0124] The receiving module 806 can receive signals from the client. These signals can indicate operational instructions for changing the map display area. The processing engine 112 can cause the client (e.g., a map application) to change the map display area according to the operational instructions. In some embodiments, the operational instructions for changing the map display area can be generated by the user dragging the map through the client's user interface (e.g., a map application).

[0125] The calculation module 808 can be used to determine the distance between the first center position and the second center position. In some embodiments, the distance between the first center position and the second center position can be the map distance between the first center position and the second center position. In some embodiments, the distance between the first center position and the second center position can be the actual distance between the first center position and the second center position according to a scale associated with the map display area.

[0126] The judgment module 810 can be used to determine whether the distance between the first center position and the second center position exceeds the second preset distance.

[0127] Figure 8B This is a block diagram of another exemplary processing engine 112 according to some embodiments of this application. Processing engine 112 may include a location acquisition module 802, a loading and display module 804, a receiving module 806, a calculation module 808, and a judgment module 810. Each of the above modules may be designed, for example, as hardware circuitry that performs certain operations according to a set of instructions stored in one or more storage media and / or a combination of hardware circuitry and one or more storage media.

[0128] The location acquisition module 802 may further include a positioning unit 8022. The positioning unit 8022 can be configured to locate the user's current city. The location acquisition module 802 can obtain the user's current location based on the current city. Further descriptions of the location acquisition module 802, loading and display module 804, receiving module 806, calculation module 808, and judgment module 810 can be found in [reference needed].

[0129] Figure 9A This is a flowchart illustrating an exemplary process for loading a site according to some embodiments of this application. In some embodiments, process 900 may be implemented as a set of instructions (e.g., an application) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112 and / or Figure 4 The module in the document can be configured to execute process 900. The operation of the process presented below is intended to illustrate the concept. In some embodiments, process 900 may be accomplished by one or more additional operations not described, and / or by one or more operations not described herein. Additionally, as... Figure 9A The order of operations shown and described below is not restrictive.

[0130] In step 902, processing engine 112 can obtain the user's current location. Processing engine 112 can designate the user's current location as a first center location on the map. As used herein, the user's current location can be the user's geographic location. The user's geographic location can be associated with and obtained from a client carried by the user. For example, processing engine 112 can obtain the user's geographic location based on the client's location information determined by the client's positioning chipset. Alternatively, the user's geographic location can be entered by the user through the client's user interface (e.g., a map application). The center location of the map can refer to the location on the map corresponding to the geometric center of the map display area. If the map display area changes, the geometric center of the map display area does not change. However, the location corresponding to the changed geometric center of the map display area can change.

[0131] In step 904, the processing engine 112 can load multiple first stations within a first preset distance from the first center location. In some embodiments, the processing engine 112 can display at least a portion of the multiple first stations located within a display area on a map. At least a portion of the multiple first stations within the map display area can also be referred to as a first group of stations.

[0132] In step 906, the processing engine 112 can receive signals from the client including operation instructions for changing the map display area. The processing engine 112 can cause the client (e.g., a map application) to change the map display area according to the operation instructions. In some embodiments, the operation instructions for changing the map display area can be generated by the user dragging and / or moving the map through the client's user interface (e.g., a map application).

[0133] In step 908, processing engine 112 can determine the distance between a first center position and a second center position associated with the changed map display area. After the user drags the map, processing engine 112 can determine the changed map display area upon receiving a signal including an operation command for changing the map display area. Processing engine 112 can designate the position corresponding to the geometric center of the changed map display area as the second center position.

[0134] In step 910, processing engine 112 can determine whether the distance between the first center position and the second center position exceeds a second preset distance. If the distance between the first center position and the second center position exceeds the second preset distance, process 900 can proceed to operation 912. If the distance between the first center position and the second center position is less than or equal to the second preset distance, process 900 can continue to execute operation 916.

[0135] In step 912, in response to determining that the distance between the first and second center locations exceeds a second preset distance, processing engine 112 can load multiple second stations located within a first preset distance from the second center location. Each of the multiple second stations can be different from one of the multiple first stations. In other words, one or more stations located within a first preset distance from the second center location among the multiple first stations loaded in operation 904 do not need to be loaded again.

[0136] In 914, the processing engine 112 can display at least a portion of a plurality of second stations and / or at least a portion of a plurality of first stations within the altered map display area. The plurality of second stations and / or at least a portion of the plurality of first stations within the altered map display area can also be referred to as a second group of stations.

[0137] In step 916, in response to determining that the distance between the first center location and the second center location is less than or equal to a second preset distance, the processing engine 112 may display at least a portion of a plurality of first stations located within the modified display area on the map. At least a portion of the plurality of first stations within the modified map display area may also be referred to as a third group of stations. In some embodiments, the third group of stations may be the same as the first group of stations. In some embodiments, a portion of the third group of stations may be the same as the first group of stations.

[0138] Specifically, when a user launches a map application from an electronic device, the processing engine 112 can locate the user's current location (i.e., the first center location of the map display area) and request access to a station interface (e.g., a station database) to obtain multiple first stations within a first preset distance from the user's current location (i.e., the first center location of the map display area). Stations may include bus stops, subway stations, etc. As used herein, the map display area may refer to the visible area of ​​the map. The processing engine 112 can display all or part of the multiple first stations (i.e., a first group of stations) located within the map display area on the map. After the user changes the map display area by dragging and / or moving the map, the processing engine 112 can determine the distance between the first center location and the second center location of the changed map display area. If the distance between the first center location and the second center location exceeds a second preset distance, the processing engine 112 can determine that the range within the first preset distance from the second center location exceeds the range within the first preset distance from the first center location, where multiple first stations have been loaded. The processing engine 112 can re-request access to the station interface (e.g., a station database) to load multiple second stations within the first preset distance from the second center location. When the processing engine 112 loads multiple first stations within a first preset distance from the first center location, it may not need to load multiple second stations. The processing engine 112 can display at least a portion of the multiple second stations and / or at least a portion of the multiple first stations (i.e., the second group of stations) within the changed display area on the client's display screen. In some embodiments, the second group of stations may include at least a portion of the multiple first stations and at least a portion of the multiple second stations within the changed map display area. In some embodiments, the second group of stations may only include at least a portion of the multiple second stations within the changed map display area. By loading only the unloaded stations within a preset distance from the center location of the map display area at a time, the network traffic consumed by the client can be reduced, and the mapping consistency between the stations displayed on the map (e.g., the visible area of ​​the map) and the corresponding stations located on the actual road can be ensured, guaranteeing the smoothness of station display.

[0139] If the distance between the first and second center locations is less than or equal to a second preset distance, the processing engine 112 can determine that the range within the first preset distance from the second center location does not exceed the range within the first preset distance from the first center location, where multiple first sites have been loaded. The processing engine 112 can load the multiple second sites within the first preset distance from the second center location without re-requesting access to the site interface (e.g., the site database). The processing engine 112 can display at least a portion of the loaded first sites (also referred to as a third group of sites) within the modified map display area, which can save network traffic on the consumer's client and improve display speed.

[0140] Each time the user drags and / or moves the map (i.e., changes the map display area), in order to load stations, the processing engine 112 can determine the distance between the current center location and the previous center location of the map display area. The processing engine 112 can display multiple stations based on a comparison between the distance and at least one predetermined threshold (e.g., a second preset distance). The processing engine 112 can display at least a portion of multiple stations (e.g., bus stops, subway stations, etc.) near the current location, and when the user drags and / or moves the map within a small area, multiple stations (e.g., multiple second stations) are not reloaded, thus ensuring a smooth user experience and the integrity of map information or data. By setting multiple predetermined thresholds (e.g., a second preset distance, etc.), when the user drags or moves the map beyond the predetermined thresholds, the processing engine 112 can reload multiple stations (e.g., multiple second stations) to ensure that the multiple stations on the display area correspond to the corresponding stations on the actual roads.

[0141] In some embodiments, the first preset distance may be the sum of the second preset distance and the distance between the first center position or the second center position and the boundary of the map display area. Further description of the first preset distance, the second preset distance, and the boundary of the map display area can be found in [reference needed]. Figure 15 More details in [the document / section].

[0142] Figure 9B This is a flowchart illustrating another exemplary process for loading a site according to some embodiments of this application. In some embodiments, process 950 may be implemented as a set of instructions (e.g., an application) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112 and / or Figure 4The module in the document can be configured to execute process 950. The operation of the process presented below is intended to illustrate the concept. In some embodiments, process 950 may be accomplished by one or more additional operations not described, and / or by one or more operations not described herein. Additionally, as... Figure 9B The order of operations shown and described below is not restrictive.

[0143] In step 901, processing engine 112 can locate the user's current city. Processing engine 112 can obtain the location information of the user's current city. This location information can be obtained from a client device carried by the user. For example, the location information of the user's current city can be determined by the positioning chipset of the client device carried by the user. Alternatively, the user can input the location information of their current city through the client's user interface (e.g., a map application).

[0144] In step 902, processing engine 112 can obtain the user's current location based on the location information of the user's current city. Processing engine 112 can designate the user's current location as the first center location of the map. As used herein, the user's current location can be the user's geographic location. The user's geographic location can be obtained from the client carried by the user based on the location information of the current city. For example, the client can locate and / or determine the user's geographic location from the current city using the client's positioning chipset.

[0145] In step 903, the processing engine 112 can load multiple first stations within a first preset distance from the first center location. In some embodiments, the processing engine 112 can display at least a portion of the multiple first stations located within a display area on a map.

[0146] In 905, the processing engine 112 can receive signals from the client, including operation instructions for changing the map display area.

[0147] In 907, the processing engine 112 can determine the distance between the first center position and the second center position associated with the changed map display area.

[0148] In 909, the processing engine 112 can determine whether the distance between the first center position and the second center position exceeds a second preset distance.

[0149] In 911, in response to determining that the distance between the first center location and the second center location exceeds a second preset distance, the processing engine 112 can load multiple second stations within the first preset distance from the second center location.

[0150] In 913, the processing engine 112 can display at least a portion of multiple second stations and / or at least a portion of multiple first stations within the altered map display area.

[0151] In step 915, in response to determining that the distance between the first center location and the second center location is less than or equal to a second preset distance, processing engine 112 can display at least a portion of the multiple first stations within the altered map display area. Further description of operations 903-915 can be found in [reference needed]. Figure 9A Detailed description of operations 904 to 916.

[0152] Figure 10 This is a block diagram of another exemplary processing engine according to some embodiments of this application. Processing engine 112 may include an acquisition module 1002, an interest point determination module 1004, a receiving module 1006, a display module 1008, a judgment module 1010, and a storage module 1012. Each of the above modules may be designed, for example, as hardware circuitry that performs certain operations according to a set of instructions stored in one or more storage media and / or a combination of hardware circuitry and one or more storage media.

[0153] The acquisition module 1002 can be used to acquire the scale of a map display area from a client. As used herein, the scale associated with a map display area can represent the relationship between ground distance (also known as actual distance) and the corresponding distance on the map (also known as map distance). In some embodiments, the scale associated with a map display area can be defined by the ratio of actual distance to map distance. The scale associated with a map display area defined by the ratio of actual distance to map distance can be greater than a constant 1. For example, if the scale associated with a map display area is equal to 10, then 1 centimeter of map distance equals 10 meters of actual distance. In some embodiments, the scale associated with a map display area can be defined by the ratio of map distance to actual distance. The scale associated with a map display area defined by the ratio of map distance to actual distance can be less than a constant 1. For example, if the scale associated with a map display area is equal to 0.01, then 1 centimeter of map distance equals 10 meters of actual distance.

[0154] In some embodiments, the acquisition module 1002 can acquire the scale associated with the map display area from a client (e.g., service requester terminal 130, service provider terminal 140) via network 120. For example, a user associated with the client can input the scale associated with the map display area via a user interface implemented on the client. As another example, the user can zoom in or out of the display area via the interface, and the acquisition module 1002 can determine the scale associated with the map display area based on the user's actions.

[0155] The acquisition module 1002 can also be configured to acquire the user's current location. As used herein, the user's current location can be the user's geographic location. The user's geographic location can be associated with and obtained from a client carried by the user. For example, the acquisition module 1002 can acquire the user's geographic location based on location information of the client determined by a set of positioning chips in the client. Alternatively, the user's geographic location can be input by the user through the client's user interface (e.g., a map application). In some embodiments, the acquisition module 1002 can acquire location information of the user's city. The location information of the user's city can be associated with and obtained from a client carried by the user. For example, the location information of the user's city can be determined by the positioning chipset of the client carried by the user. Further, the acquisition module 1002 can acquire the user's current location based on the location information of the user's current city.

[0156] The point of interest determination module 1004 can be used to determine multiple target points of interest (POIs). Points of interest may include stations (e.g., bus stops, subway stations, etc.), parking lots, supermarkets, shopping malls, restaurants, etc. In some embodiments, the station may be the uplink station or the downlink station. As used herein, the uplink station may refer to a station associated with a journey route from the origin to the destination. The downlink station may refer to a station associated with another journey route from the destination to the origin. For example, as... Figure 13 As shown, if the travel route starts from the South Gate of Agricultural University (1302) and ends at Software Park South Station (1308), the stations along the travel route from the South Gate of Agricultural University (1302) to Software Park South Station (1308) can be the up-line stations. Similarly, stations along another travel route from Software Park South Station (1308) to the South Gate of Agricultural University (1302) can be the down-line stations.

[0157] In some embodiments, multiple target points of interest (POIs) may be determined by the POI determination module 1004 based on a POI query input by a user via a client's user interface (e.g., a map application). For example, the client's user interface (e.g., a map application) may receive a signal including information about the POI query and send that signal to the POI determination module 1004. The POI determination module 1004 may retrieve and / or determine multiple candidate POIs matching the POI query from a predetermined POI database based on the POI query. In some embodiments, the POI determination module 1004 may determine and load multiple target POIs located within a preset distance from the user's current location based on the multiple candidate POIs.

[0158] In some embodiments, multiple target points of interest (POIs) can be determined based on a changed map display area or a changed current location. For example, the POI determination module 1004 can designate the user's current location as a first center location of the map display area and load multiple first POIs within a first preset distance from the first center location of the map display area. The POI determination module 1004 can determine a second center of the changed map display area and load multiple second POIs within a first preset distance from the second center location of the map display area. The POI determination module 1004 can determine the distance between the first center location and the second center location and compare the distance with a second predetermined threshold. Based on the comparison result, the POI determination module 1004 can determine multiple target POIs displayed on the map. For example, if the distance exceeds the second preset distance, the POI determination module 1004 can determine multiple target POIs from multiple second stations and / or first stations. If the distance is less than the second preset distance, the POI determination module 1004 can determine multiple target POIs from multiple first stations. A detailed description of determining multiple target POIs can be found in [reference needed]. Figure 12 The relevant description in the document.

[0159] The receiving module 1006 can be used to receive signals from a client. In some embodiments, the signal can indicate an operation instruction for changing the map display area. The receiving module 1006 can cause the client (e.g., a map application) to change the map display area according to the operation instruction. In some embodiments, the operation instruction for changing the map display area can be generated by a user dragging the map through the client's user interface (e.g., a map application). In some embodiments, the signal can indicate an operation instruction for zooming in or out of the map. The receiving module 1006 can cause the client (e.g., a map application) to zoom in or out of the map according to the operation instruction.

[0160] Display module 1008 can be configured to display at least a portion of a plurality of target points of interest on a modified map display area. In some embodiments, the plurality of target points of interest may include one or more uplink stations and one or more downlink stations. Display module 1008 may determine whether to display one or more uplink stations and one or more downlink stations based on the comparison result. For example, in response to determining that the proportion associated with the map display area is less than or equal to a first threshold, one or more uplink stations and one or more downlink stations are displayed on the map display area. In response to determining that the proportion associated with the map display area is less than the first threshold or equal to a second threshold, display module 1008 may display one or more uplink stations or one or more downlink stations from the plurality of target points of interest on the map display area. In response to determining that the proportion associated with the map display area is greater than the second threshold, display module 1008 may neither display one or more uplink stations nor one or more downlink stations from the plurality of target points of interest on the map display area.

[0161] For example, in response to determining that the proportion associated with the map display area is less than a first threshold, the display module 1008 may display one or more uplink stations and one or more downlink stations for multiple target points of interest on the map display area. In response to determining that the proportion associated with the map display area is greater than or equal to the first threshold and less than a second threshold, the display module 1008 may display one or more uplink stations or one or more downlink stations for multiple target points of interest on the map display area. In response to determining that the proportion associated with the map display area is greater than or equal to the second threshold, the display module 1008 may neither display one or more uplink stations nor one or more downlink stations for multiple target points of interest on the map display area.

[0162] In some embodiments, the display module 1008 may further determine the number of target points of interest (POIs) displayed on the map display area based on the comparison result. For example, if the proportion associated with the map display area is less than or equal to a first threshold, the display module 1008 may determine a first number of POIs on the map and display the first number of POIs on the map. If the proportion associated with the map display area is greater than the first threshold and less than a second threshold, the display module 1008 may determine a second number of POIs on the map and display the second number of POIs on the map. If the proportion associated with the map display area is greater than or equal to the second threshold, the display module 1008 may determine a third number of POIs on the map and display the third number of POIs on the map. The first number may be greater than the second number, and the second number may be greater than the third number. In some embodiments, the third number may be equal to 0.

[0163] The determination module 1010 can be configured to determine the distance between a first center location and a second center location. The determination module 1010 can compare the distance between the first center location and the second center location with a second preset distance. If it is determined that the distance between the first center location and the second center location is greater than the second preset distance, the determination module 1010 can cause the point of interest determination module 1004 to load multiple second points of interest within the first preset distance of the second center location in the map display area after the distance change. Each of the multiple second points can be different from one of the multiple first points. In other words, one or more of the multiple first points within the first preset distance from the second center location may not be reloaded.

[0164] The determination module 1010 can also be configured to compare the proportion associated with the map display area with a first threshold and / or a second threshold. In some embodiments, the first threshold may be 10, and the second threshold may be 100. For example, if the determination module 1010 determines that the proportion associated with the map display area is less than or equal to the first threshold, the display module 1008 may display the area of ​​one or more of the uplink stations and one or more of the downlink stations on the map. If the determination module 1010 determines that the proportion associated with the map display area is greater than or equal to the first threshold and less than or equal to the second threshold, the display module 1008 may display one or more of the uplink stations or one or more of the downlink stations in the map display area. If the determination module 1010 determines that the proportion associated with the map display area is greater than or equal to the second threshold, the display module 1008 may neither display one or more of the uplink stations nor one or more of the downlink stations in the map display area.

[0165] Storage module 1012 can be configured to store data and / or instructions. In some embodiments, memory 150 can store data and / or instructions that processing engine 112 can execute or use to execute the exemplary methods described in this application. For example, the user's current location, a first center location of the map, a second center location of the map, signals indicating changes to the map display area, etc., can be stored in storage module 1012. In some embodiments, memory 150 may include mass storage, removable storage, volatile read-write storage, read-only storage (ROM), etc., or any combination thereof. In some embodiments, display module 1008 can be integrated into a client (e.g., service requester terminal 130, service provider terminal 140, etc.).

[0166] Figure 11This is a flowchart illustrating an exemplary process for displaying multiple target points of interest according to some embodiments of this application. In some embodiments, process 1100 may be implemented as a set of instructions (e.g., an application program) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112 and / or Figure 4 The module in the document can be configured to execute process 1100. The operation of the process presented below is intended to illustrate the concept. In some embodiments, process 1100 may be accomplished by one or more additional operations not described herein, and / or by one or more operations not described herein. Additionally, as... Figure 11 The order of operations shown and described below is not restrictive.

[0167] In 1102, the processing engine 112 can obtain the scale of the map display area from the client. As used herein, the scale associated with the map display area can represent the relationship between ground distance (also known as actual distance) and the corresponding distance on the map (also known as map distance). In some embodiments, the scale associated with the map display area can be defined by the ratio of actual distance to map distance. The scale associated with the map display area defined by the ratio of actual distance to map distance can be greater than a constant 1. For example, if the scale associated with the map display area is equal to 10, then 1 centimeter of map distance equals 10 meters of actual distance. In some embodiments, the scale associated with the map display area can be defined by the ratio of map distance to actual distance. The scale associated with the map display area defined by the ratio of map distance to actual distance may be less than a constant 1. For example, if the scale associated with the map display area is equal to 0.01, then 1 centimeter of map distance equals 10 meters of actual distance.

[0168] In some embodiments, the scale associated with the map display area can vary with the actual distance and the unit of the map distance. For example, if the map distance is 1 cm and the actual distance is 1000 cm, the scale associated with the map display area defined by the ratio of the actual distance to the map distance can be 1000. If the map distance is 1 cm and the actual distance is 10 meters (i.e., 1000 cm), the scale associated with the map display area defined by the ratio of the actual distance to the map distance can be 10. In some embodiments, the processing engine 112 can obtain the scale associated with the map display area from a client (e.g., service requester terminal 130, service provider terminal 140) via network 120. For example, a user can input the scale associated with the map display area via a user interface (e.g., a map application) implemented on the client. Alternatively, a user can zoom in or out of the display area via an interface area, and the processing engine 112 can determine the scale associated with the map display area based on the user's actions.

[0169] In step 1104, processing engine 112 can compare the proportion associated with the map display area to one of a first threshold or a second threshold. The first threshold and / or the second threshold can be constants. In some embodiments, the second threshold can be greater than the first threshold. For example, the first threshold can be 10 and the second threshold can be 100. In some embodiments, the first threshold and / or the second threshold can be set by a user via a user interface implemented on a client. In some embodiments, the first threshold and / or the second threshold can be set according to the default settings of the online / offline service system 100. For example, processing engine 112 can set the first threshold and / or the second threshold based on the proportion associated with the map display area. If the proportion associated with the map display area is defined by the ratio of map distance to actual distance (i.e., less than 1), processing engine 112 can set the first threshold and / or the second threshold to be less than 1. If the proportion associated with the map display area is defined by the ratio of map distance to actual distance (i.e., greater than 1), processing engine 112 can set the first threshold and / or the second threshold to be greater than 1. For example, the processing engine 112 can set a first threshold and / or a second threshold based on the total number of candidate points of interest within a preset distance from the user's current location. The larger the total number of candidate points of interest, the smaller the first threshold and / or the second threshold can be.

[0170] In step 1106, the processing engine 112 may determine, based on the comparison result, whether to display multiple Points of Interest (POIs) on the map display area. POIs may include stations (e.g., bus stops, subway stations, parking lots, supermarkets, shopping malls, restaurants, etc.). In some embodiments, the station may be the uplink station or the downlink station. As used herein, the uplink station may refer to a station associated with a journey route from the origin to the destination. The downlink station may refer to a station associated with another journey route from the destination to the origin. For example, if the journey route starts at 1302, South Gate of Agricultural University, and ends at 1308, South Station of Software Park, as... Figure 13 As shown, the stations along the route from the South Gate of the Agricultural University (1302) to the destination, Software Park South Station (1308), can be the upstream stations.

[0171] Another route from Software Park South Station 1308 to Agricultural University South Gate 1302 could be the downlink station. In some embodiments, processing engine 112 may determine multiple target points of interest (POIs) based on queries about POIs. These queries may be entered by a user via a client's user interface (e.g., a map application). Processing engine 112 may retrieve and / or determine multiple candidate POIs that match queries about POIs from a predetermined POI database. In some embodiments, processing engine 112 may determine and load multiple target POIs within a preset distance from the user's current location based on the multiple candidate POIs. In some embodiments, processing engine 112 may receive signals including operational instructions for changing the map display area or the user's current location, such as dragging the map display area. Multiple target POIs may be determined based on the changed map display area or the changed current location. For example, processing engine 112 may designate the user's current location as a first center location of the map display area and load multiple first POIs within a first preset distance from the first center location of the map display area. Processing engine 112 can determine a second center of the map display area and load multiple second points of interest (POIs) within a first preset distance from the second center location. Processing engine 112 can determine the distance between the first and second center locations and compare the distance with a second predetermined threshold. Based on the comparison result, processing engine 112 can determine to display multiple target POIs on the map. For example, if the distance exceeds the second preset distance, processing engine 112 can determine multiple target POIs from multiple second POIs and / or multiple first POIs. If the distance is less than the second preset distance, processing engine 112 can determine multiple target POIs from multiple first POIs. A detailed description of determining multiple target POIs can be found in [link to relevant documentation]. Figure 12 Found it.

[0172] In some embodiments, multiple target points of interest may include multiple uplink stations and multiple downlink stations. Processing engine 112 may determine whether to display multiple uplink stations and multiple downlink stations based on the comparison result. For example, processing engine 112 may cause the client to display multiple uplink stations and multiple downlink stations on the map response display area to determine that the proportion associated with the map display area is greater than or equal to a first threshold. Processing engine 112 may cause the client to display multiple uplink stations or multiple downlink stations on the map response display area to determine that the proportion associated with the map display area is greater than a first threshold and less than or equal to a second threshold. Processing engine 112 may cause the client to neither display multiple uplink stations nor multiple downlink stations on the map response display area to determine that the proportion associated with the map display area is greater than a second threshold.

[0173] For example, processing engine 112 may cause the client to display multiple upstream and downstream stations on the map response display area to determine that the proportion associated with the map display area is smaller than a first threshold. Processing engine 112 may also cause the client to display multiple upstream or downstream stations on the map response display area to determine that the proportion associated with the map display area is greater than or equal to the first threshold and less than a second threshold. Processing engine 112 may further cause the client to not display multiple upstream or downstream stations on the map response display area to determine that the proportion associated with the map display area is greater than or equal to the second threshold.

[0174] In some embodiments, processing engine 112 may further determine the number of target points of interest displayed on the map display area based on the comparison result. For example, if the proportion associated with the map display area is less than or equal to a first threshold, processing engine 112 may determine a first number of target points of interest on the map and cause the client to display the first number of target points of interest on the map. If the proportion associated with the map display area is greater than the first threshold and less than a second threshold, processing engine 112 may determine a second number of target points of interest displayed on the map and cause the client to display the second number of target points of interest on the map. If the proportion associated with the map display area is greater than or equal to the second threshold, processing engine 112 may determine a third number of target points of interest displayed on the map and cause the client to display the third number of target points of interest on the map. The first number may be greater than the second number, and the second number may be greater than the third number. In some embodiments, the third number may be equal to 0. In some embodiments, the first number, the second number, and / or the third number may be determined by the user via the client's user interface or according to the default settings of system 100.

[0175] In some embodiments, the processing engine 112 may enable a client to display information or data associated with multiple target points of interest on a map. Exemplary information or data associated with target points of interest may include the name of the target point of interest, an icon representing the target point of interest, or any other identifier used to distinguish the target point of interest from other points of interest.

[0176] It should be noted that the foregoing is provided for illustrative purposes only and is not intended to limit the scope of this application. Various modifications and changes can be made by those skilled in the art based on the description in this application. However, these modifications and changes will not depart from the scope of this application. For example, process 1100 may also include determining the user's current location and determining multiple target points of interest based on the user's current location.

[0177] Figure 12 This is a flowchart illustrating an exemplary process for loading and displaying multiple target points of interest according to some embodiments of this application. In some embodiments, process 1200 may be implemented as a set of instructions (e.g., an application program) stored in memory 150, memory 260, or memory 390. CPU 210, CPU 340, processing engine 112, and / or Figure 4 The modules within can execute this set of instructions, and when the instructions are executed, CPU 210, CPU 340, processing engine 112 and / or Figure 4 The module in the document can be configured to execute process 1200. The operation of the process presented below is intended to illustrate the concept. In some embodiments, process 1200 may be accomplished by one or more additional operations not described herein, and / or by one or more operations not described herein. Additionally, as... Figure 12 The order of operations shown and described below is not restrictive.

[0178] In 1202, processing engine 112 can obtain the current location of the user associated with the client on the map display area. As used herein, the user's current location can be the user's geographic location. The user's geographic location can be associated with and obtained from the client carried by the user. For example, processing engine 112 can obtain the user's geographic location based on the client's location information determined by the client's positioning chipset. As another example, the user's geographic location can be entered by the user through the client's user interface (e.g., a map application).

[0179] In step 1204, the processing engine 112 can designate the user's current location as the first center location of the map. In some embodiments, the center location of the map can refer to the location on the map corresponding to the geometric center of the map display area. If the map display area changes, the geometric center of the map display area may remain unchanged, but the location on the map corresponding to the geometric center of the map display area may change.

[0180] In step 1206, the processing engine 112 can load multiple first points of interest (POIs) within a first preset distance from the first center location. POIs may include stations (e.g., bus stops, subway stations, etc.), parking lots, supermarkets, shopping malls, restaurants, etc. In some embodiments, the processing engine 112 can retrieve and / or determine multiple first POIs from a POI database. The processing engine 112 can also acquire information and / or data associated with each of the multiple first POIs. The information and / or data associated with a first POI may include the name of the first POI, the address of the first POI, and an identifier (e.g., an icon) associated with the first POI.

[0181] In step 1208, processing engine 112 can acquire signals from the client. These signals can indicate operational instructions for changing the map display area. Processing engine 112 can then cause the client (e.g., a map application) to change the map display area according to the operational instructions. In some embodiments, a user can generate operational instructions for changing the map display area by dragging the map via the client's user interface (e.g., a map application). In some embodiments, a user can move their current location (e.g., as shown in the image) via the client's user interface (e.g., a map application). Figure 13 Point A shown in the diagram is used to generate operation instructions for changing the map display area.

[0182] In 1210, processing engine 112 can obtain a second center position of the map based on the changed map display area. In some embodiments, in response to a user dragging the map or moving the current position, processing engine 112 can determine the changed map display area. Then, processing engine 112 can designate the position corresponding to the geometric center of the changed map display area as the second center position. In some embodiments, processing engine 112 can designate the moved current position as the second center position of the changed map display area.

[0183] In 1212, processing engine 112 can determine the distance between a first center position and a second center position. In some embodiments, the distance between the first center position and the second center position can be the map distance between the first center position and the second center position on the map. Processing engine 112 can determine the map distance between the first center position and the second center position based on the pixel coordinates of the client's display (e.g., CSS pixel coordinates). In some embodiments, the distance between the first center position and the second center position can be the actual distance corresponding to the map distance between the first center position and the second center position. By way of example only, processing engine 112 can determine the actual distance between the first center position and the second center position by multiplying the corresponding map distance by a scale associated with the map display area.

[0184] In step 1214, the processing engine 112 can compare the distance between the first center position and the second center position with a second preset distance. The second preset distance can be determined based on the first preset distance. In some embodiments, the first preset distance can be the sum of the second preset distance and the distance between the first center position or the second center position and the boundary of the map display area (e.g., as shown in the image). Figure 15 The boundary of the display area is shown by the dashed line. The distance between the first center position or the second center position and the boundary of the map display area can be the minimum distance from the first center position or the second center position to the boundary of the map display area in the horizontal or vertical direction. Further descriptions of the first preset distance and the second preset distance can be found in [reference needed]. Figure 15 The relevant description in the document.

[0185] In 1216, processing engine 112 can determine multiple target points of interest based on the comparison results. In response to determining that the distance between the first center position and the second center position exceeds a second preset distance, processing engine 112 can load multiple second points of interest within a first preset distance from the second center position. Each of the multiple second points of interest can be different from one of the multiple first points of interest, meaning that if a first point of interest loaded in operation 1206 is within the first preset distance from the second center position, then that first point of interest may not be loaded again in operation 1216.

[0186] In some embodiments, the processing engine 112 can determine one or more target points of interest by determining whether the distance between a first center location and a second center location exceeds a second preset distance. If the distance between the first center location and the second center location exceeds the second preset distance, the processing engine 112 can determine that at least a portion of one or more second points of interest and at least a portion of one or more first points of interest within the changed display area are one or more target points of interest. If the distance between the first center location and the second center location is less than the second preset distance, the processing engine 112 can determine that at least a portion of one or more first points of interest located within the changed map display area are one or more target points of interest.

[0187] In 1218, processing engine 112 can cause the on-demand service platform to display at least a portion of multiple target points of interest on a changed display area of ​​the map. In some embodiments, processing engine 112 can cause the on-demand service platform to display information and / or data associated with each of the target points of interest in a changed map display area. Exemplary information and / or data associated with target points of interest may include the name of the target point of interest, the identifier of the target point of interest, etc.

[0188] In some embodiments, processing engine 112 may cause the on-demand service platform to display at least a portion of one or more target points of interest on the modified map display area according to a proportion associated with the modified map display area. For example, the multiple target points of interest may include multiple uplink stations and multiple downlink stations. In response to determining that the proportion associated with the modified map display area is less than or equal to a first threshold, processing engine 112 may cause the on-demand service platform to display one or more of the uplink stations and one or more of the downlink stations on the modified map display area. In response to determining that the proportion associated with the modified map display area is greater than the first threshold and less than or equal to a second threshold, processing engine 112 may cause the on-demand service platform to display one or more of the uplink stations or one or more of the downlink stations on the modified map display area. In response to determining that the proportion associated with the modified map display area is greater than the second threshold, processing engine 112 may cause the on-demand service platform to neither display one or more of the uplink stations nor one or more of the downlink stations on the modified map display area.

[0189] For example, in response to determining that the proportion associated with the changed map display area is less than a first threshold, processing engine 112 can cause the on-demand service platform to display one or more uplink stations and one or more downlink stations for one or more target points of interest on the changed map display area. In response to determining that the proportion associated with the changed map display area is greater than or equal to the first threshold and less than a second threshold, processing engine 112 can cause the on-demand service platform to display one or more uplink stations or one or more downlink stations for the changed map display area. In response to determining that the proportion associated with the changed map display area is greater than or equal to the second threshold, processing engine 112 can cause the on-demand service platform to display one or more uplink stations or one or more downlink stations for multiple target points of interest on the changed map display area.

[0190] In some embodiments, the first threshold may be 10, and the second threshold may be 100. In some embodiments, if the scale associated with the modified map display area is equal to 10, then 1 centimeter of map distance equals 10 meters of actual distance. If the scale associated with the modified map display area is equal to 100, then 1 centimeter of map distance equals 100 meters of actual distance. It should be noted that the actual distance is in meters, while the map distance is in centimeters. In some embodiments, the units of actual distance and map distance may be unified, and the values ​​of the first and second thresholds may be changed accordingly.

[0191] It should be noted that the foregoing is provided for illustrative purposes only and is not intended to limit the scope of this application. Various modifications and changes can be made by those skilled in the art based on the description of this application. However, these modifications and changes will not depart from the scope of this application. For example, process 1200 may also include displaying multiple points of interest within a display area on a map for the client.

[0192] Figure 13 These are schematic diagrams illustrating exemplary display interfaces of map applications according to some embodiments of this application. Figure 13As shown, multiple stations (e.g., Agricultural University South Gate 1302, Shangdi 10th Street 1304, Xierqi Station 1306, Software Park South Station 1308, etc.) and the user's current location (represented by point A) are displayed on the map display area. The scale associated with the map display area represents the relationship between the ground distance (also called the actual distance) and the corresponding distance on the map (also called the map distance). For example, the map distance could be 1 centimeter, the actual distance could be 100 meters, and the scale associated with the map display area could be the ratio of the map distance of 1 centimeter to the actual distance of 100 meters, i.e., 0.01. Another example is that the scale associated with the map display area could be the ratio of the actual distance of 100 meters to the map distance of 1 centimeter, i.e., 100.

[0193] In some embodiments, such as Figure 13 The multiple stations shown on the map can be as follows: Figure 9A as well as Figure 9B At least a portion of the plurality of first stations shown. The plurality of stations may be within a first preset distance from the user's current location (i.e., a first center location of the map display area). In some embodiments, such as Figure 13 The multiple stations shown on the map can be as follows: Figure 9A as well as Figure 9B The map display area can be a plurality of second stations and / or at least a portion of a plurality of first stations. After the user moves the map display area, the map display area can change, and the center position of the changed map display area (i.e., the second center position) can differ from the first center position. If the distance between the first center position and the second center position exceeds a second preset distance, a plurality of second stations can be loaded. At least a portion of the plurality of second stations and at least a portion of the plurality of first stations located within the changed display area can be displayed on the map. If the distance between the first center position and the second center position is less than or equal to the second preset distance, at least a portion of the plurality of first stations located within the changed display area can be displayed on the map. The first preset distance can be the sum of the second preset distance and the distance between the first center position or the second center position and the boundary of the map display area. Further description of the first preset distance, the second preset distance, and the boundary of the map display area can be found in [reference needed]. Figure 15 Related descriptions in Chinese.

[0194] Figures 14A-14C As shown in some embodiments of this application Figure 13 The diagram shown illustrates the display of multiple stations on a map. (For example...) Figure 13As shown, after the user zooms in on the map, the processing engine 112 can execute different display modes for multiple sites based on the range of the scale associated with the changed map display area. The range of the scale associated with the changed map display area can be combined with... Figure 6 The first and second thresholds described in section 7 are used to define the range. For example, if the first threshold equals 10, the first range can be 0 to 10. If the second threshold equals 100, the second range can be 10 to 100, and the third range can be any constant value from 100 to greater than 100. If the ratio associated with the changed map display area is less than or equal to 10 (i.e., the change ratio associated with the changed map display area is within the first range), then the processing engine 112 can display multiple upstream stations and multiple downstream stations within the map display area. Figure 14A As shown, both the upstream station, South Gate 1404 of the Agricultural University, and the downstream station, South Gate 1402 of the Agricultural University, are displayed on the enlarged map display area. If the scale associated with the changed map display area is greater than 10 and less than or equal to 100 (i.e., the scale of change associated with the changed map display area is within a second range), then the processing engine 112 can display the upstream station or the downstream station on the map display area. Figure 14B As shown, the processing engine 112 displays only the upstream station (e.g., the south gate of the Agricultural University 1404) on the scaled map display area, instead of displaying all the upstream and downstream stations. This avoids station overlap caused by displaying both upstream and downstream stations on the map. If the scale associated with the changed map display area is greater than 100 (i.e., the change scale associated with the changed map display area is within a third range), the processing engine 112 hides the upstream and downstream stations. Figure 14C As shown, stations around the user's current location are not displayed in the zoomed-out map display area.

[0195] Figure 15 These are schematic diagrams illustrating exemplary display interfaces of map applications according to some embodiments of this application. Figure 15 As shown, Figure 13The first preset distance is denoted by R, the second preset distance by L2, and the distance between the first or second center position (represented by point B) and the boundary of the map display area (represented by the dashed line) is denoted by L1. The first preset distance can be the sum of the second preset distance and the distance between the first or second center position and the boundary of the map display area. For example, the first preset distance R can be equal to 10 centimeters, representing an actual distance of 1000 meters. The second preset distance L2 can be equal to 7 centimeters, representing an actual distance of 700 meters. The distance L1 between the first or second center position and the boundary of the map display area is equal to 3 centimeters, representing an actual distance of 300 meters.
