Description

Technical Field

[0001] The present invention relates to a geographic map data system, and more particularly to a geographic map data system that can simplify the data recording process and simultaneously display different heights or different depths of selected points on the same layer. Background Art

[0002] The Geographic Information System (GIS) is established by collecting, storing, updating, integrating, converting and displaying real-world geographic data or spatial data, so that users can easily analyze through this system. Currently, the Geographic Information System can be used for environmental and natural resource surveys or for the design of urban plans such as residential areas, protected areas, roads or park lands.

[0003] Geographic Information Systems use different layer files that are sorted and stacked one on top of the other. Traditionally, when users perform queries, they can only view them in the order in which the layer files are arranged. For example, Figure 1 The diagram shows the stacking diagram of image layers of the existing geographic map data (T), which are stacked from layer P5 to layer P1 in the order of arrangement. Each layer represents an image layer of different height or depth. Therefore, it is difficult for the user to directly understand the changes in the height or depth of the terrain in the same location from a single layer file, and it is necessary to select different layer files to know. If there are many targets to be observed, it is not possible to get the desired information in a short time. Moreover, when facing high-resolution image layers, the data storage capacity is huge and the computer calculation is more complicated. If this traditional layer file display method is used, it is often time-consuming and inconvenient. Even for the same longitude and latitude location, the user cannot know how many locations there are at the same longitude and latitude through the image layer stacking diagram. For example, it is impossible to know how many floors a building has, what facilities are set up on the floors, etc. through the image layer stacking diagram.

[0004] Therefore, the present invention is to explain how to effectively improve the inconvenience of traditional geographic information system layer display through innovative invention design, which is still a problem that developers and researchers in related industries need to continue to work hard to overcome and solve. Summary of the invention

It should be noted that the content of the reserved word 2001 is different from and not identical to the content of the string 2002 or the description message 2003.

[0064] Next, in order to further understand the purpose, features, and intended effects of the present invention, the programming language and computer program code are presented in a tabular form below to illustrate the scope of practical application, but it is not intended to limit the scope of the present invention in any form.

[0065] Please refer to FIG. 5A to FIG. 7 As shown, Figure 6 and Figure 7The third and fourth diagrams are diagrams of the recording method of the data recording module 200 of a preferred embodiment of the present invention. The reserved character 2001 is set to #EASE_LAYER, corresponding to the vertical layer information 105 of the specific longitude and latitude coordinates, and is pre-defined as the content of the selection field 102 of the geographic diagram data 101.

[0066] Please refer to Figure 3 and Figure 5A In the data recording module 200, the reserved characters 2001 are different from the strings 2002 corresponding to the attribute fields 103 of longitude, latitude, building name and floor position and the strings 2002 of the longitude and latitude coordinate positions. In the same longitude and latitude coordinate positions, a string 2002 mainly composed of the reserved characters 2001 is added. The reserved characters 2001 can be set to #EASE_LAYER. When the description message 2003 is 1, the corresponding floor position is the 1st floor, and when the description message 2003 is 2, the corresponding floor position is the 2nd floor. Please refer to Figure 5A and Fig. 8A , Figure 8B , 1 or 2 is displayed in the selection field 102 respectively, and the user can directly add a string 2002 mainly composed of reserved characters 2001 and its description message 2003. In actual implementation, there is no restriction on the user to record data in the order of floor positions. Figure 5B , the floor positions of the third and fourth rows are not recorded in sequence.

[0067] Please refer to Figure 3 and Figure 6 In the data recording module 200, the reserved characters 2001 are added to the description information 2003. For example, #EASE_LAYER1 is added after "commercial building" to correspond to the floor position of the first floor, and #EASE_LAYER2 is added after "commercial building" to correspond to the floor position of the second floor. In addition, Figure 6 and Fig. 8A , Figure 8B As shown, 1 or 2 is displayed in the selection field 102 respectively. In actual implementation, there is no restriction on the user to record data in the order of floors, and there is no need to consider whether the longitude and latitude coordinates are consistent, and the reserved character 2001 is directly added to the corresponding attribute information 104.

[0068] Please refer to Figure 3 and Figure 7In the data recording module 200, the reserved characters 2001 are added to the string 2002. The user can set the recording rules of the reserved characters for the same longitude and latitude coordinates in advance. For example, at the longitude 121.5645553715582 and the latitude 25.03381144589455, 1# is added in front of the building name and 1# is added in front of the floor position to represent that the floor position of the commercial building is the 1st floor, and 2# is added in front of the building name and 2# is added in front of the floor position to represent that the floor position of the commercial building is the 2nd floor. In actual implementation, there is no restriction on the user to record data in the order of floors.

[0069] The recording methods of the different data recording modules 200 of the present invention can simplify the method of inputting information, so that the user can record the reserved characters 2001 in a variety of ways according to actual needs, and enable the geographic map system 1 to correctly display the vertical layered information 105 of the selected point.

[0070] Please continue to refer to Figure 3 The processor 201 can execute the operation instruction and the content of the data recording module 200, and generate the content of the data recording module 200 in the map database 10. The processor 201 can be exemplified by but not limited to a microcontroller, a microprocessor, a central processing unit (CPU), an application specific integrated circuit (ASIC), a digital logic circuit, a digital signal processor, a field programmable gate array (FPGA) and / or other hardware components with arithmetic processing functions. Each processor 201 can be coupled to another by an application specific integrated circuit, a digital logic circuit, a field programmable gate array and / or other hardware components.

[0071] In one embodiment of the present invention, the geographic map data system 1 further includes a distance calculation module 202 and a merge display module 203. The distance calculation module 202 is used to calculate the distance between the longitude and latitude coordinates of the selected point and the longitude and latitude coordinates of another selected point. The distance is the shortest path length. When the distance is less than a distance threshold, the merge display module 203 determines whether the coordinate names 106 of the two are the same. If the coordinate names 106 of the two are the same, they are merged and displayed as one selected point to reduce Figure 2The geographic diagram data 101 displays too many selected points. If the coordinate names 106 of the two are different, each selected point is displayed separately so that the user can distinguish the content of each selected point. When the distance is greater than a distance threshold, the merge display module 203 is not executed, so that the selected point and the other selected point are displayed separately.

[0072] In one embodiment of the present invention, the geographic map system 1 further includes a warning module 204. When the vertical layered message 105 is the depth position, if the attribute information 104 corresponding to the depth position is lower than a first depth threshold, or the attribute information 104 of the depth position is higher than a second depth threshold, the second depth threshold is greater than the first depth threshold, and the first depth threshold and the second depth threshold can be formulated according to actual needs, the warning module 204 sends a warning message to remind the user to pay attention to the coordinate name 106 of the selected point and the vertical layered message 105. For example, the selected point is the groundwater position, the vertical layer information 105 is the depth position, the groundwater level is the attribute information 104 corresponding to the depth position, and the multiple selected fields 102 are the order of measuring the groundwater level each time. If the groundwater level is lower than a first depth threshold, the warning module 204 sends a warning message to remind the user to pay attention to whether the groundwater position has over-pumping or the water level is too low; if the groundwater level is higher than a second depth threshold, the warning module 204 sends a warning message to remind the user to pay attention, which can be used as a warning, such as to prevent the groundwater from being too low and causing the pump to fail to operate smoothly. The warning message can be formulated according to actual needs.

[0073] In one embodiment of the present invention, the geographic map data system 1 further includes a search module 205. The search module 205 can search by a keyword or a range value to obtain search results. When the search module 205 searches by a keyword, it can include fuzzy search and precise search. Precise search is based on the condition of completely matching the keyword, while fuzzy search can search for synonyms of the keyword, or partial text, numbers or symbols that match the keyword. For example, please refer to Figure 3 and Figure 5A , the reserved characters 2001, the character string 2002 or the description information 2003 of the data recording module 200 can be searched by keywords to obtain the searched position or number of entries, so that the user can conveniently check or record the reserved characters 2001, the character string 2002 or the description information 2003. Alternatively, the selected point or the content of the selected field 102 in the geographic diagram data 101 can be searched, so that the user can quickly find the selected point, the content of the selected field 102 or the number of entries to be observed or analyzed.

[0074] In one embodiment of the present invention, the geographic map system 1 further includes a label module 206. The label module 206 can select one or a combination of a color, a graphic, and a pattern as a mark of the selected point. In actual implementation, when the selected point is a groundwater location, the user can set a groundwater pattern for the selected point, or when the selected point is a school, the user can set a suitable school pattern for the selected point to facilitate the user to identify the object represented by the selected point. Figure 4 As shown, each selected point A1, A2, A3, A4, A5, A6, A7 represents a different building, and some selected points display different patterns, wherein different patterns represent attribute information 104 having different vertical layered information 105 (such as Fig. 8A , Figure 8B ), for example, if the buildings have the same number of floors, or the heights of the floors of the buildings are similar or the same, the same pattern is displayed, such as selecting points A2, A3, and A4. Otherwise, different patterns are displayed, such as selecting points A1, A5, A6, and A7, so that the user can quickly understand the relative relationship between the selected points.

[0075] In one embodiment of the present invention, a display preference module 207 is further included. The display preference module 207 can display the attribute fields 103 and the attribute information 104 of multiple selection fields 102 of a single selection point at the same time or display the attribute fields 103 and the attribute information 104 of one of the selection fields 102 of a single selection point at the same time. In actual implementation, the user can adjust the display quantity of the selection field 102 content in a single selection point according to the needs. For example, when the selection point is a groundwater location and has multiple selection fields 102, the user can select some of the selection fields 102 that he is interested in or all of the selection fields 102 to display the attribute fields 103 and the attribute information 104.

[0076] In one embodiment of the present invention, the geographic map system 1 further comprises a chart module 208 for generating a chart for the relationship between the attribute information 104 of the vertical layered information 105 of at least one selected point and the change over time. Fig.11As shown, it is a usage state diagram of the chart module 208 of the geographic map data system of one preferred embodiment of the present invention. The selected point is the groundwater position, the attribute information 104 of the vertical layered information 105 is the value of the groundwater level, and the chart can be presented in the form of a curve chart, a line chart, a histogram, a graphic or text. The curve chart in this embodiment shows the water level changes of a single selected point from October 2013 to January 2019 in different periods, and the number of data is the number of times the water level is measured; the maximum water level value, the minimum water level value, the standard deviation and the average water level value are obtained by calculating and analyzing the values ​​of the water level measured each time. The user can use the chart module 208 to perform statistical analysis on the attribute information 104 of the vertical layered information 105 of the selected point in a specific period to observe the trend or phenomenon of water level changes.

[0077] In one embodiment of the present invention, the geographic map data system 1 further includes a selection module 209, which can select at least one of the selection points in the geographic map data 101. When the selection module 209 adopts the click selection mode, the user can select by clicking; when the selection module 209 adopts the sketch selection mode, the user can select by sketching; when the selection module 209 adopts the drag selection mode, the user can select by dragging; when the selection module 209 adopts the area selection mode, such as Figure 3 and Fig.10 As shown, the user can select a regular closed figure 2090 such as a circle, an ellipse, a rectangle, or an irregular closed figure 2090 through the area selection module 209; when the selection module 209 adopts the preset action selection mode, the user can select through a motion sensor sensing the user's preset action, and the preset action can be, for example, but not limited to, a gesture action or a human body action, etc. The gesture action can be a change in the three-dimensional coordinates of the position of the finger, the palm, and the knuckles, and the geographic diagram data 101 and the displayed content are moved, rotated, and scaled. The motion sensor senses the gesture action or the human body action through the principle of laser interruption. For example, when the gesture action or the human body action When the hand enters the projection range of the laser, the motion sensor can detect the light spots generated on the hand or human body when the light is blocked, and the amount of light reflected by these light spots (reflecting the changed part) and the time difference (reflecting the depth). Then, based on the continuously obtained light signals, the change in the three-dimensional coordinates caused by the gesture or human body movement is obtained, and the geographic diagram data 101 and its displayed content are moved, rotated and scaled; or when the selection module 209 adopts the sensing selection mode, the user can make a selection by sensing the user's gesture through a touch screen, and the touch screen can be exemplified by but not limited to a capacitive touch screen, an acoustic touch screen, an optical touch screen or a pressure touch screen, etc.

[0078] In one embodiment of the present invention, the geographic map data system 1 further includes a storage module 210. The storage module 210 can be a memory for storing the data recording module 200, the distance calculation module 202, the merged display module 203, the warning module 204, the search module 205, the label module 206, the display preference module 207, the chart module 208, the selection module 209 or a combination thereof. The processor 201 can read the content of the storage module 210 and execute it. The storage module 210 can be exemplified by, but not limited to, a hard disk drive (HDD), a solid state drive (SSD), a silicon disk drive (SDD), a read-only memory (ROM), a random access memory (RAM), a compact disk read-only memory (CD-ROM), a floppy disk, a magnetic tape, and an optical data storage device. In actual implementation, the user can read the content of the geographic map data system 1 stored in the storage module 210 through the processor 201 and execute it.

[0082] One of the purposes of the present invention is to simultaneously display vertical layered information of different heights or depths in the same layer, so as to reduce the time and manpower consumed by the traditional method of constantly selecting different layer files to obtain such information. Furthermore, the display method of the present invention can also reduce the time required for the computer to perform calculations when calculating high-resolution image layers due to continuous selection in the past, so that users can more conveniently and quickly understand the target location information they want to observe.

[0083] One of the purposes of the present invention is to use the distance calculation module of the present invention in combination with the merge display module to determine whether the content of the input selection point positions with similar distances needs to be displayed merged or separately. This can not only simplify the number of selection points during display, but also allow users to quickly understand the relationship between different selection point positions.

[0084] One of the purposes of the present invention is to simplify the way of inputting information through the data recording module of the present invention, so that users can record according to actual needs by adding different reserved characters, or quickly find the location of the information to be input from a large number of strings or description messages through reserved characters, and enable the geographic map system to correctly display the attribute information field of the selected point. In addition, different attribute fields and attribute information fields can be added to the same selection field, so that the content contained in each vertical layered message is different.

[0085] One of the purposes of the present invention is to simultaneously display vertical layered information of target selection points, so that users can observe and analyze at different vertical heights or different vertical depths, for example: the changes in water levels of the same well at different periods, or the changes in terrain height of specific selection points at different periods.
