[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of methods consistent with some aspects of this application as detailed in the appended claims.
[0056] The method provided in this application embodiment can be executed by a terminal device, which refers to an electronic device with data computing, processing and storage capabilities, such as a PC (Personal Computer), tablet computer, smartphone, wearable device, intelligent robot, vehicle terminal, etc.
[0057] The technical solution of this application will be described and illustrated below through several embodiments.
[0058] Please refer to Figure 1 This document illustrates a flowchart of a map-based grid display method according to an embodiment of this application. In this embodiment, the method is primarily illustrated by its application to the terminal device described above. The method may include at least one of the following steps (110-130).
[0059] Step 110: Receive the instruction to create the first grid on the electronic map.
[0060] In some embodiments, an electronic map is a map that can be stored and displayed on a terminal device (such as on the display screen of the terminal device). An electronic map may include photographs of real maps, as well as elements such as lines, graphics, images, and text. In some embodiments, by performing operations such as zooming in, zooming out, and moving the displayed map, display changes such as zooming in, zooming out, and moving the electronic map can be achieved, i.e., controlling the display scale and display area of the electronic map.
[0061] The technical solutions provided in this application aim to play a key role in the grid-based management of intelligent platforms. This application relates to Geographic Information Systems (GIS) and digital map production. By integrating map services, this application can achieve efficient division of jurisdictional areas, creating multiple grid-like units. Each grid-like unit can contain geographic location information, as well as information on population, land, resources, events, and organizations. All this information can be organized systematically in the unit's attribute information column, facilitating quick access and effective management of relevant information for users.
[0062] In some embodiments, in response to a user's grid editing operation, an instruction is generated to create a first grid on an electronic map. In some embodiments, the instruction may carry the area range and display style of the first grid to be generated. In some embodiments, the display style may include the grid's border width, color, line style, etc., and may also include the grid's internal color, transparency, etc.
[0063] Step 120: As instructed, generate the area range of the first grid on the electronic map and the display style of the first grid.
[0064] In some embodiments, a first grid is generated on an electronic map according to the area and display style of the first grid indicated in the instruction. In some embodiments, the first grid is displayed above the display hierarchy of the electronic map. In some embodiments, the instruction may also include labeling content facing the first grid, such as at least one of text labels, image labels, and numerical labels.
[0065] Step 130: If there is an overlapping area between the first grid and other grids at the same level, display a first prompt message to prompt the user to adjust the area range of the first grid.
[0066] In some embodiments, the mesh can be divided into multiple different levels, and there should be no overlapping areas between meshes of the same level. Therefore, if there is an overlapping area between the area range of the first mesh indicated in the instruction and other meshes, the mesh cannot be generated directly according to the area range indicated in the instruction.
[0067] In some embodiments, the method further includes:
[0068] 1. Obtain the area range of the first grid and other grids at the same level;
[0069] 2. Compare the area of the first grid with the area of other grids at the same level. If there is a point in the first grid that is located within the area of other grids at the same level, then it is determined that there is an overlapping area between the first grid and other grids at the same level.
[0070] In this embodiment, if there is a point in the first grid that is located in another grid of the same level, it means that the first grid and the other grid of the same level have an overlapping area. In order to avoid grid division confusion, the overlapping area of the first grid and other grids can be removed, thereby improving the accuracy of grid division.
[0071] In some embodiments, the first prompt message may be displayed in the form of text and / or voice. In some embodiments, when the first prompt message contains text, the first prompt message may be displayed as a pop-up window.
[0072] In some embodiments, when a user clicks the save button, the system will determine whether the user meets the criteria for adding a grid map based on the corresponding method. If the user does not meet the criteria, a pop-up message (i.e., the first prompt message) will be sent to remind the user. After the user successfully saves the map, the map's coordinate data will be associated with the corresponding grid data on the left.
[0073] In some embodiments, after a user adds a grid, the system will automatically locate the largest grid within the user's permissions each time they enter the electronic map, allowing the user to edit, drag, zoom, and perform other operations on the electronic map containing the grid. In some embodiments, richer interactive effects can be achieved by listening to relevant events (such as listening to user operations on the electronic map containing the grid).
[0074] In summary, the technical solution provided in this application, by setting up overlap judgment logic between grids, avoids overlap between grids of the same level on the electronic map, thereby improving the accuracy of grid labeling on the electronic map.
[0075] In some possible implementations, the electronic map includes a parent grid and at least one child grid corresponding to the parent grid, with the child grid located within the area of the parent grid.
[0076] In some embodiments, there may be a parent-child relationship (or a superior-subordinate relationship) between different levels of grids. A lower-level grid must be located within its corresponding higher-level grid (such as a parent grid); or in other words, each grid with a lower-level grid (i.e., a child grid) must have its lower-level grid located within the area of that grid, thereby avoiding grid information confusion.
[0077] In some embodiments, the method further includes the following steps:
[0078] 1. When the area of the parent grid changes, compare the area of the child grid with the changed area of the parent grid;
[0079] 2. If there is a region in the child mesh that is outside the changed region of the parent mesh, adjust the region of the child mesh to obtain the changed child mesh, which is located within the changed region of the parent mesh.
[0080] In some embodiments, if the area of the parent mesh changes, the area of the child mesh of the parent mesh is compared with the changed area of the parent mesh. If the comparison result indicates that there is a child mesh outside the changed area of the parent mesh, the child mesh also needs to be adjusted accordingly to ensure that the child mesh is still within the changed area of the parent mesh and does not exceed the parent mesh, thereby ensuring the containment relationship between the parent mesh and the child mesh, avoiding mesh information confusion, and improving the accuracy of mesh division.
[0081] In some embodiments, when the area of the parent mesh changes, comparing the area of the child mesh with the changed area of the parent mesh includes: when the edge coordinates of the parent mesh change, comparing the edge coordinates of the child mesh with the changed edge coordinates of the parent mesh.
[0082] In some embodiments, when there are regions in the child grid that are outside the changed region of the parent grid, adjusting the region of the child grid to obtain the changed child grid includes: when there are coordinate points in the child grid that are outside the changed region of the parent grid, reassigning the coordinate points in the child grid that are outside the changed region of the parent grid to obtain the changed child grid.
[0083] In some embodiments, child grids are automatically planned to ensure they always remain within the parent grid's area. In other embodiments, a listener event is added to the parent grid. When the parent grid's coordinates change, the changed coordinates are compared with those of the child grid. If the child grid's coordinates exceed those of the parent grid, the child grid's coordinates are reassigned. This automatically adjusts the child grid to fit within the parent grid's area, improving grid partitioning efficiency.
[0084] In some embodiments, after comparing the region extent of the child grid with the changed region extent of the parent grid, if the child grid is still within the changed region extent of the parent grid, the region extent of the child grid remains unchanged.
[0085] In some embodiments, automatic adjustment of sub-mesh can be achieved through the following steps:
[0086] (1) A change in the region extent of the parent grid was detected;
[0087] (2) Obtain the coordinates of each point of the parent grid and the coordinates of each point of the child grid after the change and compare them;
[0088] (3) If the coordinates of the child grid exceed the changed parent grid, the coordinates of the child grid that exceeds the parent grid will be assigned new coordinate values so that the coordinates of the new child grid form a new child grid and the new child grid is located within the area of the changed parent grid.
[0089] (4) If none of the coordinate points of the child grid exceed the area of the changed parent grid, then retain the original coordinate points of the child grid, and retain the child grid formed by the coordinate points of these child grids.
[0090] In the above embodiments, a specific implementation method is provided for determining whether a child grid needs to be adjusted when the area of the parent grid changes: by comparing and calculating with each coordinate point of the child grid, it is determined whether the area of the child grid needs to be adjusted, thereby making a simple and convenient judgment and adjusting the grid.
[0091] In some embodiments, after displaying the first prompt message, the method may further include the following steps:
[0092] 1. In response to the first operation on the first grid, generate the automatically adjusted area of the first grid;
[0093] 2. Display the first grid according to the area range automatically adjusted by the first grid;
[0094] Among them, the area range of the first grid after automatic adjustment has removed the overlapping area compared to the area range indicated by the command.
[0095] In some embodiments, if there is an overlapping area between the first grid and other grids at the same level, the overlapping area is determined as the area of the other grid according to the first-come-first-served principle, and the overlapping area is automatically removed from the area range of the first grid indicated in the instruction, so as to obtain the area range of the first grid after automatic adjustment, thereby avoiding the overlap of the same grid.
[0096] In some embodiments, such as Figure 2 As shown, the data on the left is displayed within the polygon component of the electronic map. The displayed organizational tree and the grid area displayed on the electronic map are determined based on the permissions of the currently logged-in user. In some embodiments, functions such as location retrieval, map grid area editing, and storage can be added.
[0097] In some embodiments, such as Figure 3 As shown, the method may also include the following steps:
[0098] 1. Import and configure amap-jsapi-loader;
[0099] 2. Load the plugin and set the map parameters;
[0100] 3. Determine if a grid map has been added. If yes, proceed to step 4; otherwise, proceed to step 6.
[0101] 4. Display the electronic fence;
[0102] 5. The page will locate the current city;
[0103] 6. Search for and locate the city;
[0104] 7. Create and display a grid map;
[0105] 8. Add text markers;
[0106] 9. Encapsulate methods for determining network overlap, etc.
[0107] 10. The user clicks "Save";
[0108] 11. Determine if the conditions for adding are met. If yes, proceed to step 12; otherwise, proceed to step 13.
[0109] 12. Link grid data with map coordinates;
[0110] 13. Pop-up notification;
[0111] 14. Allows editing of grid maps.
[0112] In some embodiments, the electronic map's API (Application Programming Interface) is introduced into the project and the map API key is configured. The necessary plugins, such as map address auto-completion plugin, address retrieval plugin, map polygon editing plugin, and map polygon drawing plugin, are loaded on the page, and the map center point and initial zoom level are set.
[0113] In some embodiments, clicking the "Add" button on the left-hand tree structure node allows users to add a grid name, grid responsibilities, and associate the added information with the organization. Clicking "Save" saves the data to the server. Users can also perform editing and deletion operations using other buttons.
[0114] In some embodiments, the current company's grid structure tree is returned based on the data interface. If grids have been added, the corresponding electronic fences will be displayed on the electronic map; if no grids have been added, the electronic map can add the corresponding grid information and grids through the Add Map button.
[0115] In some embodiments, when a user enters the page, the company and address of the currently logged-in user will be obtained based on the user's information. The map will automatically locate the current city based on the obtained address information. If the company and address are not obtained, the user can search for the city through the search box and display the searched information through address retrieval and address completion. After selection, the user will be located in the currently selected area.
[0116] In some embodiments, a map drawing polygon plugin is used to create a grid map. The style of the grid map can be set, such as border color, border width, fill color, and fill transparency. The created polygon object is added to the map by calling the map object's `add` method. After the grid is added to the map and displayed, users can intuitively see its position and shape. Users can also add text markers to the grid on the map based on the created grid name. A marker or overlay can be added at the center of the grid or a specific location, and its displayed text content can be set so that the target grid can be quickly located even when the electronic map is zoomed out to a certain level.
[0117] In some embodiments, a grid can also be added to the 3D (three-dimensional) view. In some embodiments, a custom map layer is created in the electronic map, and WebGL is used to draw 3D graphics in the custom map layer. The acquired 3D coordinate data is then fused with the grid data so that the grid can also be displayed in the 3D view.
[0118] In some embodiments, users can switch to a 3D satellite layer by clicking the satellite view function in the map toolbar, thereby optimizing the user experience.
[0119] In some embodiments, a grid can be drawn in a 3D satellite layer by plotting 3D graphics. The grid in the 3D view also includes parent and child grids. However, the coordinates that form these grids require the addition of Z-axis data. Furthermore, the Z-axis data needs to be considered during actual parent grid monitoring and automatic planning.

[0129] In some embodiments, the region comparison module is used to compare the edge coordinates of the child grid with the changed edge coordinates of the parent grid when the edge coordinates of the parent grid change.
