[0020] Maps are an important form of display. Most of the daily map displays are based on the various provincial administrative regions of the country. In the logistics industry, the various provincial administrative regions of the country and the cities / districts under each provincial administrative region are used as the basis for regional division.

[0021] At present, electronic maps in the logistics field will make custom area divisions based on administrative divisions, and clearly show the business situation of each area by marking each area; through mouse operation, relevant detailed information of the selected area can also be viewed and related operations can be performed, but some custom areas are relatively small in area, or there will be multiple custom areas with relatively small areas adjacent to each other, resulting in a poor viewing and operation experience for users.

[0022] The existing technology has the problem of poor user experience in viewing and operating electronic maps in the logistics field.

[0023] The electronic map control method of the present application obtains a preset geographic data format of the electronic map, the map longitude and latitude of each preset area, and the longitude and latitude coordinates of the mouse movement; based on the preset geographic data format and the map longitude and latitude of each preset area, multiple logistics business areas with boundaries are determined; based on each logistics business area, the map longitude and latitude corresponding to each logistics business area, and the preset area condition, a logistics display area set is determined; if the map longitude and latitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is enlarged, and the business information of the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is displayed; based on the logistics display area set and the moving path formed by the multiple longitude and latitude coordinates of the mouse movement, the electronic map is controlled to load the logistics display area and the preset surrounding area corresponding to the moving path according to the preset settings. Since the logistics business area that meets the preset area requirement is set to be able to be enlarged and displayed following the longitude and latitude coordinates of the mouse movement, and the logistics display area and the preset surrounding area corresponding to the mouse moving path can be loaded according to the preset settings, the user's experience of viewing and operating the electronic map in the logistics field is greatly improved, which is convenient for logistics companies to coordinate according to the business information of each area, and improves the logistics efficiency of the logistics industry.

[0024] The technical solution of the present application is described below through specific embodiments.

[0025] First, as Figure 1 As shown, the embodiment of the present application provides a method for controlling an electronic map, including:

[0026] S100, obtaining a preset geographic data format of an electronic map, the map longitude and latitude of each preset area, and the longitude and latitude coordinates of the mouse movement.

[0027] In one embodiment, the preset geographic data format is Geojson format, wherein Geojson format is a format for encoding various geographic data structures, a geographic spatial information data exchange format based on JavaScript Object Notation (JSON for short), and Geojson format is an open standard geographic data format that can be used to describe various geographic information on a map. In Geojson format, custom fences can be created by defining various types of geometric objects such as points, lines, and polygons. Longitude and latitude are the combination of longitude and latitude to form a coordinate system, called a geographic coordinate system.

[0028] In one embodiment, based on the fence data in Geojson format of the national electronic map, the fence data in Geojson format of the logistics electronic map is obtained, the customized business areas of the logistics company are formed based on the national administrative regions, and the map latitude and longitude of each customized business area of ​​the logistics company is obtained based on the map latitude and longitude of each national administrative region. For example, the customized Sichuan business area is formed by merging Sichuan Province and Tibet Autonomous Region in the national administrative region; the customized Guangzhou business area is formed by merging Guangzhou City, Qingyuan City, and Shaoguan City.

[0029] In one embodiment, the entire electronic map is defined as a basic map container. The map engine of the basic map container loads the Geojson format data of the custom business area for map rendering and displays the fence of the custom business area. At the same time, the mouse movement event in the basic map container is monitored. The mouse movement event will trigger the corresponding event function, thereby obtaining the corresponding mouse latitude and longitude coordinates of the mouse in the basic map container.

[0030] S200, determining a plurality of logistics business areas with boundaries based on a preset geographic data format and the longitude and latitude of a map of each preset area.

[0031] In one embodiment, based on a preset geographic data format and the map longitude and latitude of each preset area, multiple logistics business areas with boundaries are determined, which is conducive to accurately determining a customized logistics business area on an electronic map.

[0032] In the application, based on the fence data in Geojson format of the national electronic map and combined with the needs of logistics companies, more than 40 logistics business areas were customized. The scope of each logistics business area is very different from the administrative division of the country. For example, since the customized Guangzhou logistics business area is formed by the merger of Guangzhou, Qingyuan and Shaoguan, the administrative division has two boundaries, which is not convenient for displaying the Guangzhou logistics business area and related business information.

[0033] In one embodiment, based on a preset geographic data format and the longitude and latitude of a map of each preset area, multiple logistics business areas with boundaries are determined, including: based on the preset geographic data format and the longitude and latitude of a map of each preset area, each logistics business area with only one boundary is determined by a region tree method, thereby avoiding the existence of multiple boundaries in each logistics business area, facilitating the statistics of various data in each logistics business area, and improving the accuracy of each logistics business area on the electronic map.

[0034] In one embodiment, based on the preset geographic data format and the map longitude and latitude of each preset area, the Guangzhou logistics business area with only one boundary is determined through the regional tree method. This eliminates the two internal boundaries of the administrative area and only retains the boundary between the Guangzhou logistics business area and other logistics business areas, which is conducive to the display of the Guangzhou logistics business area and related business information, as well as the operation of the Guangzhou logistics business area.

[0035] In one embodiment, the region tree is an R-tree (Region Tree), and based on the preset geographic data format and the longitude and latitude of the map of each preset region, each logistics business area with only one boundary is determined by the region tree method, including: based on the preset geographic data format and the longitude and latitude of the map of each preset region, the longitude and latitude of the boundary of the logistics business area is determined to form a boundary set; all boundaries in the boundary set are traversed, and the longitude and latitude of any two boundaries are judged by the R-tree method whether there is overlap in longitude and latitude; if there is overlap in longitude and latitude of the two boundaries, the two boundaries are combined into a composite boundary; after the composite boundary is formed, the two boundaries before the combination are deleted, and the composite boundary is added to the boundary set, and the above steps are repeated until each logistics business area with only one boundary in the boundary set. It can be understood that each logistics business area with only one boundary is converted into fence data in a new Geojson format for subsequent calls.

[0036] S300, determining a set of logistics display areas based on each logistics business area, the longitude and latitude of the map corresponding to each logistics business area, and a preset area condition.

[0037] In one embodiment, a logistics display area set is determined based on each logistics business area, the map longitude and latitude corresponding to each logistics business area, and a preset area condition. The logistics display area set is a set of magnifying glass display areas, which is conducive to magnifying and displaying logistics business areas that are not convenient to display, thereby improving the user experience.

[0038] In one embodiment, based on each logistics business area, the longitude and latitude of the map corresponding to each logistics business area, and a preset area condition, a logistics display area set is determined, including:

[0039] Based on each logistics business area, the map longitude and latitude corresponding to each logistics business area and the preset area conditions, the logistics display area set is determined through the bounding box tree structure.

[0040] In one embodiment, based on each logistics business area, the map longitude and latitude corresponding to each logistics business area, and the preset area conditions, a set of logistics display areas is determined through a bounding box tree structure, which improves the division and query efficiency of the logistics display areas and improves the user experience.

[0041] In one embodiment, Figure 2 As shown, based on each logistics business area, the map longitude and latitude corresponding to each logistics business area, and the preset area conditions, the logistics display area set is determined through a bounding box tree structure, including:

[0042] S310: If the area of ​​one or more adjacent logistics business areas meets a preset area condition, set the one or more adjacent logistics business areas as logistics display areas.

[0043] In one embodiment, if the area of ​​a logistics business zone meets the preset area condition, or if the sum of the area areas of multiple adjacent logistics business zones meets the preset area condition, setting a logistics business zone or multiple adjacent logistics business zones as a logistics display area is beneficial to reducing the amount of calculation and improving the response speed of the electronic map.

[0044] In one embodiment, the preset area condition is that the area of ​​a logistics business area or the sum of the areas of multiple adjacent logistics business areas is less than or equal to 5% of the area of ​​the electronic map, which facilitates the definition of the logistics display area, improves the response speed of the electronic map, and improves the user experience.

[0045] S320: Determine a rectangular boundary box corresponding to any logistics display area based on each logistics display area and the longitude and latitude of the map corresponding to each logistics display area.

[0046] In one embodiment, based on each logistics display area and the map longitude and latitude corresponding to each logistics display area, a rectangle inscribed in the logistics display area is formed according to the maximum map longitude and latitude and the minimum map longitude and latitude of the logistics display area, thereby determining the rectangular bounding box corresponding to any logistics display area.

[0047] S330: Form leaf nodes of a bounding box tree based on the rectangular bounding box corresponding to any logistics display area.

[0048] S340, forming a bounding box tree structure based on the rectangular bounding boxes of the leaf nodes of each layer, and the bounding box tree structure is a corresponding logistics display area set.

[0049] In one embodiment, the rectangular bounding boxes corresponding to the adjacent leaf nodes of each layer are merged into the leaf nodes of the previous layer until all the rectangular bounding boxes are merged into an overall rectangular bounding box, and the largest rectangular bounding box is the root node of the bounding box tree, so the rectangular bounding boxes of the leaf nodes of each layer form a bounding box tree structure. Since the bounding box tree structure includes all the logistics display areas, that is, the bounding box tree structure is a corresponding set of logistics display areas, it is convenient to search for logistics display areas in the bounding box tree structure, improve the response speed of electronic map reading, and improve the user experience.

[0050] S400: If the longitude and latitude of the map of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is enlarged, and the business information of the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is displayed.

[0051] In one embodiment, if the map longitude and latitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is enlarged, and the business information of the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is displayed. This is conducive to enlarging the logistics business area with a small area, facilitating user display and operation, improving the user experience, and also facilitating the logistics company to handle related business and improve logistics efficiency.

[0052] In one embodiment, a logistics display area corresponding to the longitude and latitude coordinates moved by the mouse is enlarged, and a magnifying glass container is defined. The magnifying glass container is a container rendered in the basic map container using absolute positioning (Position: absolute) in Cascading Style Sheets (CSS), wherein the Cascading Style Sheets are used to render the style of the label on the enlarged page; the initial value of the transparency (Opacity) in the Cascading Style Sheets properties of the magnifying glass container is set to 0 (i.e., completely opaque); the trigger point events (Pointer-events) in the Cascading Style Sheets properties of the magnifying glass container are set to none, which does not affect the interaction between the user and the basic map container (i.e., the electronic map), wherein Pointer-events is a pointer attribute, which is used to control whether a specific graphic element can become the target of the pointer event under preset conditions; the Z-axis level of the magnifying glass container is greater than the basic map container level, for example, the Z-axis level of the magnifying glass container is set to the basic map container level plus 1.

[0053] In one embodiment, if the map longitude and latitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, that is, the mouse movement event has been triggered, the longitude and latitude corresponding to the longitude and latitude coordinates of the mouse movement are in the map longitude and longitude of the logistics display area set.

[0054] In one embodiment, Figure 3As shown, if the map latitude and longitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is enlarged, and the business information of the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is displayed, including:

[0055] S410: If the map longitude and latitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, vector slices are performed on the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement through a quadtree structure according to a preset magnification ratio.

[0056] In one embodiment, if the map longitude and latitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is vector sliced ​​through a quadtree structure according to a preset magnification ratio, thereby improving the efficiency of finding the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement, improving the response speed of the electronic map, and improving the user experience.

[0057] In one embodiment, Figure 4 As shown, if the map latitude and longitude of the logistics display area set includes the longitude and latitude coordinates of the mouse movement, vector slicing of the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement is performed through a quadtree structure according to a preset magnification ratio, including:

[0058] S411, based on the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement and the preset magnification ratio, determine the package rectangle of the logistics display area after the package is magnified as the root node of the quadtree.

[0059] In one embodiment, based on the logistics display area corresponding to the longitude and latitude coordinates of the mouse movement, the maximum longitude and latitude and the minimum longitude and latitude of the logistics display area are determined; the maximum longitude and latitude and the minimum longitude and latitude form a package rectangle of the logistics display area; the package rectangle is enlarged based on a preset magnification ratio to determine the enlarged package rectangle, and the package rectangle of the logistics display area after the package is enlarged is determined as the root node of the quadtree.

[0060] S412: Recursively divide the map area corresponding to the wrapping rectangle into four child nodes layer by layer until the area of ​​the map area corresponding to any child node is less than or equal to the map area threshold.

[0061] In one embodiment, the map area corresponding to the enclosing rectangle is recursively divided into 4 child nodes layer by layer, that is, the map area corresponding to the enclosing rectangle of the root node is divided into 4 sub-map areas, 1 sub-map area corresponds to 1 child node, and then the sub-map area corresponding to each child node of the first layer is further divided into 4 grandchild map areas, until the area of ​​the map area corresponding to any child node is less than or equal to the map area threshold.

[0062] In one embodiment, one map area is divided into four sub-map areas, specifically by obtaining the coordinates of the center point of the map area in the horizontal and vertical directions, and extending the map area in the horizontal and vertical directions with the center point coordinates as the center, so as to divide the enclosing rectangle corresponding to the map area into four sub-enclosing rectangles of equal area, and each sub-enclosing rectangle corresponds to one subnode.

[0063] In one embodiment, the map area threshold is 20% of the electronic map area before zooming in, or the map area threshold is 5% of the electronic map area after zooming in, which is conducive to dividing the area of ​​the map area corresponding to any child node according to the electronic map, avoiding the map area of ​​each child node being too large, resulting in incomplete information, and improving the display accuracy of the electronic map.

[0064] S413: Encapsulate the code and boundary coordinates of the wrapping rectangle corresponding to any child node into a rectangle object.

[0065] In one embodiment, the package rectangle corresponding to any child node has a unique code, and the code and boundary coordinates of the package rectangle corresponding to any child node are encapsulated as a rectangular object, so as to facilitate accurate and rapid identification of the child node corresponding to the code, the package rectangle corresponding to the child node, and the logistics display area corresponding to the package rectangle.

[0066] S414, forming a quadtree structure based on the rectangular objects of each layer.

[0067] S420, based on the result of the vector slice and the preset magnification ratio, the logistics display area corresponding to the longitude and latitude coordinates where the mouse is moved is magnified, and the business information of the logistics display area corresponding to the longitude and latitude coordinates where the mouse is moved is displayed.

[0068] In one embodiment, the preset zoom ratio ranges from 2 to 4, which is helpful to limit the magnification ratio of the magnifying glass within a reasonable range of the electronic map, avoiding incomplete information display due to excessive zoom ratio, or unclear displayed information due to excessive zoom ratio, thereby improving the user experience.

[0069] In one embodiment, the business information includes the name, revenue, achievement rate, customer complaint rate and corresponding trend indicators of the logistics display area.

[0070] In one embodiment, Figure 5 As shown, the Ningbo Logistics Exhibition Area is enlarged and the business information of the Ningbo Logistics Exhibition Area is displayed.

[0071] S500, based on the logistics display area set and the moving path formed by a plurality of mouse movement longitude and latitude coordinates, control the electronic map to load the logistics display area and the preset surrounding area corresponding to the moving path according to the preset settings.

[0072] In one embodiment, based on a set of logistics display areas and a moving path formed by multiple mouse movement longitude and latitude coordinates, the electronic map is controlled to load the logistics display area and the preset surrounding area corresponding to the moving path according to preset settings, which is conducive to enlarging and displaying the loaded logistics display area and the preset surrounding area along the moving path formed by the mouse movement.

[0073] In one embodiment, the preset settings include preset magnification transparency attribute settings, preset coordinate conversion settings, and preset display content loading settings.

[0074] In one embodiment, Figure 6 As shown, based on the logistics display area set and the moving path formed by multiple mouse movement longitude and latitude coordinates, the electronic map is controlled to load the logistics display area and the preset surrounding area corresponding to the moving path according to the preset settings, including:

[0075] S510, based on the logistics display area set and the moving path formed by multiple mouse movement longitude and latitude coordinates, determine the logistics display area and the preset surrounding area corresponding to the moving path, wherein the preset surrounding area is the surrounding area outside the logistics display area from the mouse movement longitude and latitude coordinates to the preset field of view radius.

[0076] In one embodiment, the area formed by moving the mouse from the longitude and latitude coordinates to the preset field of view radius is less than or equal to 15% of the area of ​​the electronic map, thereby preventing the logistics display area of ​​the magnifying glass from being too large, causing the preset surrounding area to also become larger, reducing the sense of inappropriate proportion between the magnifying glass area and the electronic map, and improving the user experience.

[0077] S520, based on the logistics display area and the preset surrounding area corresponding to the moving path, control the electronic map to load the logistics display area and the preset surrounding area corresponding to the moving path according to the preset magnification transparency attribute setting, the preset coordinate conversion setting, and the preset display content setting.

[0078] In one embodiment, the preset magnification transparency attribute is set to:

[0079] If the longitude and latitude coordinates of the mouse are not within the longitude and latitude of the map in the logistics display area, set the transparency (Opacity) in the cascading style sheet properties of the magnifying glass container to 0 (i.e. completely opaque);

[0080] If the longitude and latitude coordinates of the mouse are within the longitude and latitude coordinates of the map in the logistics display area, the transparency (Opacity) in the cascading style sheet properties of the magnifying glass container is set to 1 (ie, completely transparent).

[0081] In one embodiment, the preset coordinate conversion is set to convert the longitude and latitude coordinates of the mouse movement into absolute coordinates of the electronic map, where the absolute coordinates are the coordinates of the electronic map in a coordinate system formed by a horizontal coordinate axis x and a vertical coordinate axis y in a display device.

[0082] In one embodiment, the preset display content is set to determine the logistics display area and the preset surrounding area corresponding to the moving path, and the logistics display area and the preset surrounding area corresponding to the moving path are displayed according to a preset magnification ratio.

[0083] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
