Description

Technical Field

[0001] The invention discloses a method and a device for displaying map points of interest in a configured aggregated manner, and relates to the technical field of maps. Background Art

[0002] In business systems involving electronic maps, points of interest are a common form of data display. When there are too many points of interest within a certain range, points of interest are usually aggregated to optimize the display effect and reduce unnecessary rendering. Points of interest aggregation is usually implemented in two forms: server-side point of interest aggregation and browser-side point of interest aggregation. The server-side point of interest aggregation is aggregated by the server according to the aggregation algorithm. The advantage is high aggregation efficiency, but the generated aggregation point usually does not contain the point of interest information aggregated by the aggregation point. The browser-side point of interest aggregation is aggregated by the browser according to the aggregation algorithm. The advantage is that the aggregation point contains the point of interest information aggregated by the aggregation point, but when there are too many points of interest, there is a problem of low aggregation efficiency. Summary of the invention

[0003] In view of the problems of the prior art, the present invention provides a method and device for displaying map POI configuration-based aggregation, which realizes flexible switching between two aggregation forms, namely, POI aggregation on the server side and POI aggregation on the browser side, through parameter configuration, taking into account both the efficiency of POI aggregation and the integrity of information obtained from the aggregation points, thereby improving the response speed and stability of the system.

[0004] The specific scheme proposed by the present invention is:

[0005] The present invention provides a method and device for displaying points of interest on a map in a configured aggregated manner, including:

[0006] Step 1: Configure a specific map level as the threshold for switching the form of POI aggregation.

[0007] Step 2: Actively obtain and store the configured threshold through the browser.

[0008] Step 3: Obtain the electronic map level in time through the browser, compare the size with the stored threshold, and obtain the point of interest set from the server based on the comparison result, and process and render it for display. Specifically:

[0009] If the electronic map level is less than or equal to the threshold, a set of points of interest in the form of points of interest aggregation implemented on the server side within the current field of view of the map is obtained from the server side, and rendered and displayed on the browser side;

[0010] If the electronic map level is greater than the threshold, the unaggregated POI set within the current field of view of the map is obtained from the server, and the unaggregated POI set is aggregated on the browser side using the POI aggregation implementation on the browser side to generate an aggregated POI set, which is then rendered and displayed.

[0011] Furthermore, in step 3 of the map point of interest configuration aggregation display method, the timing for obtaining the electronic map hierarchy through the browser is when the electronic map posture changes. The electronic map posture includes the electronic map hierarchy, the center point of the electronic map, the up and down pitch angles of the electronic map, the left and right tilt angles of the electronic map, and the horizontal flip angle of the electronic map.

[0012] Furthermore, when obtaining the POI set from the server in step 3 of the map POI configuration aggregation display method, a map range is specified, where the map range refers to a specific data structure consisting of the upper left corner coordinate value and the lower right corner coordinate value of the rectangular map field of view.

[0013] Furthermore, in step 3 of the method for displaying map points of interest in a configured aggregated manner, the points of interest set displayed by browser rendering are divided into: ordinary points of interest, pseudo-aggregated points of interest, and true aggregated points of interest according to the interaction form.

[0014] By clicking on a common POI, you can obtain the POI attribute information, which includes basic spatial information and other descriptive information. By clicking on a pseudo-aggregate POI, you can control the map to zoom to a specified level. By clicking on a true-aggregate POI, you can obtain the attribute information of all POIs contained in the true-aggregate POI.

[0015] The present invention also provides a map point of interest configuration aggregation display device, including a configuration module, a storage module and an analysis and rendering module.

[0016] The configuration module configures a specific map level as the threshold for switching the form of POI aggregation.

[0017] The storage module actively obtains and stores the configured thresholds through the browser.

[0018] The analysis and rendering module obtains the electronic map level in time through the browser, compares the size with the stored threshold, obtains the point of interest set from the server according to the comparison result, and processes and renders it for display, specifically:

[0019] If the electronic map level is less than or equal to the threshold, a set of points of interest in the form of points of interest aggregation implemented on the server side within the current field of view of the map is obtained from the server side, and rendered and displayed on the browser side;

[0020] If the electronic map level is greater than the threshold, the unaggregated POI set within the current field of view of the map is obtained from the server, and the unaggregated POI set is aggregated on the browser side using the POI aggregation implementation on the browser side to generate an aggregated POI set, which is then rendered and displayed.

[0021] Furthermore, the analysis and rendering module of the map point of interest configuration aggregation display device obtains the electronic map level through the browser when the electronic map posture changes. The electronic map posture includes the electronic map level, the center point of the electronic map, the up and down pitch angles of the electronic map, the left and right tilt angles of the electronic map, and the horizontal flip angle of the electronic map.

[0022] Furthermore, when the analysis and rendering module of the map interest point configuration aggregation display device obtains the interest point set from the server, it specifies the map range, and the map range refers to a specific data structure composed of the upper left corner coordinate value and the lower right corner coordinate value of the rectangular map field of view.

[0023] Furthermore, the analysis and rendering module of the map interest point configuration aggregation display device renders and displays the interest point set through the browser end, and divides it into: ordinary interest points, false aggregation interest points and real aggregation interest points according to the interaction form.

[0024] By clicking on a common POI, you can obtain the POI attribute information, which includes basic spatial information and other descriptive information.

[0025] By clicking on the pseudo-aggregated point of interest, you can control the map to zoom to a specified level.

[0026] By clicking on a true aggregated point of interest, you can obtain the attribute information of all the points of interest contained in the true aggregated point of interest.

[0027] The benefits of the present invention are:

[0028] It can flexibly control the use of two aggregation forms: server-side POI aggregation and browser-side POI aggregation, and realize the complete information display of aggregated POI, which improves the efficiency of POI aggregation and effectively improves the response speed and stability of the system.
