[0002] In today's digital age, the display of map data plays a vital role in many fields, such as navigation, geographic information systems, urban planning, etc. However, there are many significant problems with existing map data display technologies.

[0003] Traditional map image display methods usually rely on a large amount of data to construct and present map images. These data cover extremely detailed geographic information, including but not limited to topography, building outlines, road details, vegetation distribution, etc. In practical applications, in order to ensure the integrity and accuracy of map display, the system often needs to obtain and process massive amounts of data. This demand for excessive data directly leads to a substantial increase in data redundancy. A large amount of duplicate and unnecessary data is stored and transmitted, which not only takes up valuable storage space, but also causes serious resource waste in the process of data processing and transmission. From the perspective of computing power, processing such large and redundant data requires a lot of computing resources. This means that the system needs a more powerful processor and more memory to cope with data processing and rendering, which increases hardware costs and energy consumption. In addition, too much data will also lead to a longer response time for map display, reducing the user experience. In scenarios such as real-time navigation that require high response speed, this delay may cause great inconvenience to users and even safety hazards.

[0004] In summary, the existing map data display method has the problems of excessive data demand, high data redundancy and low display efficiency. Summary of the invention

[0028] Embodiment 1

[0029] Figure 1 A flowchart of a method for displaying map data provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of displaying map data. The method can be executed by a device for displaying map data. The device for displaying map data can be implemented in the form of hardware and / or software. The device for displaying map data can be configured in a terminal or server with a map data display function.

[0030] like Figure 1 As shown, the method includes:

[0031] S110, obtaining local coordinate system cutting rules and slice row and column numbers, and confirming the target data range according to the local coordinate system cutting rules and slice row and column numbers.

[0032] Among them, the local coordinate system cutting rules refer to a series of specifications and requirements formulated for cutting geographic spatial data into slices of specific size and shape in a specific local coordinate system; illustratively, in the local coordinate system of a certain city, the local coordinate system cutting rules are: the cutting scale is stipulated to be 1:5000, the slice size is 1024×1024 pixels, and the overlapping area between slices is 5%.

[0033] Furthermore, the slice row and column number refers to a unique identifier assigned to each slice when slicing geographic data, which is used to determine its position in the overall data.

[0034] S120 , after converting the target data range into target rectangular data, acquiring target map data matching the target rectangular data through GPS.

[0035] The target data range is a specific area that matches the row and column numbers of the slice and needs to be processed or related data is obtained; further, the target rectangular data refers to the data format in which the target data range is converted into a rectangular shape.

[0036] The step of converting the target data range into target rectangular data includes: processing the target range data using a preset function for creating a spatial range to obtain target rectangular data matching the target range data.

[0037] Specifically, the function for creating a spatial range can be: ST_MakeEnvelope(float xmin, floatymin, float xmax, float ymax, integer srid=unknown) function. It should be noted that since the function for creating a spatial range is a mature prior art and relevant personnel in this field should understand it, the use of the function for creating a spatial range will not be described in detail here; further, the function for creating a spatial range can be used to process the target range data into spatial geometric coordinates, that is, target rectangular data; for example, if there is a set of target range data (734958.6, 624841.4, 839829.5, 729712.3), the target range data is processed through ST_MakeEnvelope(float xmin, floatymin, float xmax, float ymax, integer srid=unknown) function, the target rectangle data matching the target range data can be obtained as 010300000001000000050000033333333DD6D2641CDCCCC.

[0038] Furthermore, target map data matching the target rectangular data is obtained through GPS, including: obtaining a target rectangular range based on the target rectangular data; collecting a target image matching the target rectangular range in real time through GPS; and using a pre-configured MVT geometric format conversion function to convert the target image into target map data for output.

[0039] In a specific implementation scenario of this embodiment, first, the target rectangular range is determined based on the target rectangular data. The target rectangular range is a specific geographical area clearly defined in a rectangular form. For example, in urban construction planning, the rectangular range corresponding to a specific block. Then, with the help of GPS, real-time acquisition is performed to obtain a target image that matches the target rectangular range. The target image here refers to image data that can reflect the geographic information within the specific rectangular range. For example, a real-time image containing geographic elements such as roads and buildings. Then, the pre-configured MVT (MapboxVector Tile) geometry format conversion function is used to convert the collected target image into target map data and output it. The MVT geometry format conversion function is a tool function specifically used to convert image data in a specific format into a map data format. For example, the ST_AsMVTGeom (geometry geom, box2d bounds, integer extent = 4096, integer buffer = 256, boolean clip_geom = true) function preset in the geographic information processing software.

[0040] S130: Acquire a target vector slice based on the target map data, and render the target vector slice according to a preset rendering rule to obtain a target map image and display it.

[0041] Wherein, acquiring the target vector slice based on the target map data includes: using a preset MVT format function to process the target map data to obtain the target vector slice.

[0042] Furthermore, the MVT format function is a function specifically used to convert map data in a specific format into a vector slice format, for example, the ST_AsMVT (anyelementrow, text name, integer extent, text geom_name) function configured in professional geographic information processing software.

[0043] Specifically, the rendering rules include at least one of icon configuration, text size, text color, transparency, graphic fill color and border color; wherein, icon configuration refers to the settings of the shape, style, detailed features and other aspects of various icons used in the map, such as icons identifying places, icons representing specific functional areas, etc.; for example, an icon for a shopping mall can be configured as a specific building appearance icon; text size refers to the size specification of the text displayed on the map, for example, the size of the place name text can be set differently according to its importance or the size of the display area; text color refers to the color presented by the text in the map, for example, the names of important places can be displayed in eye-catching red, and ordinary places can be displayed in black; transparency refers to the degree of transparency of certain elements in the map, for example, certain layers or marks can be set to a certain transparency to better display the underlying map information; graphic fill color is for the graphic area in the map, such as the internal fill color of a specific administrative area, functional area, etc., for example, a park area can be filled with green; border color is the color presented by the graphic border, for example, the outline border of a lake can be set to blue.

[0044] Optionally, after rendering the target vector slice according to preset rendering rules and obtaining and displaying the target map image, it also includes: starting timing after obtaining the target map image; when it is detected that the timing duration exceeds a preset time interval, returning to execute the operation of obtaining target map data matching the target rectangular data through GPS, so as to update the currently displayed target map image.

[0045] Among them, timing refers to the recording and measurement of the passage of time. For example, an electronic clock or a timing module in a computer program is used to accurately record the passage of time; further, when it is detected that the duration of the timing exceeds a preset time interval, the operation process of obtaining the target map data matching the target rectangular data through the global positioning system (GPS) is returned to execute; further, the preset time interval is a specific time period set in advance. For example, it can be set to 5 minutes, 10 minutes, etc. Through such operations, the currently displayed target map image is updated. Updating means replacing old data with newly acquired and processed data to ensure the timeliness and accuracy of the map image.

[0046] It should be noted that the ST_MakeEnvelope(float xmin,float ymin,float xmax,float ymax,integer srid=unknown) function, ST_AsMVTGeom(geometry geom,box2d bounds,integer extent=4096,integer buffer=256,boolean clip_geom=true) function mentioned in the above steps and

[0047] The ST_AsMVT (anyelement row, text name, integer extent, text geom_name) functions are all mature existing technologies, so this embodiment does not elaborate on the principles or uses of the above functions.

[0048] The technical solution of the embodiment of the present invention first obtains the local coordinate system cutting rules and slice row and column numbers, and confirms the target data range according to the local coordinate system cutting rules and slice row and column numbers, then converts the target data range into target rectangular data, obtains target map data matching the target rectangular data through GPS, and finally obtains target vector slices based on the target map data, and renders the target vector slices according to preset rendering rules to obtain and display the target map image, thereby realizing the display of map data, improving the display efficiency of map data, and reducing the data demand and data redundancy generated during the map data display process.
