Embodiment 1

[0043] Such as figure 2 As shown, the system 200 for partial rendering on the map includes: a server 202 and a client 204 of the website. The working process of the system 200 for local rendering on the map can be as follows:

[0044] S1: The client 204 determines the center point of the search according to the user's operation command, where the determination of the center point can be realized by the user inputting the coordinate information of the point, or by the user figure 1 The click operation shown on the map is realized, wherein the determination of the search range can be determined by the search radius input by the user and the coordinate information of the above-mentioned center point; the client determines the search range according to the user's operation command, wherein the The determination of the search range can be determined by the search radius input by the user;

[0045] S2: The server 202 receives the coordinates of the center point and the informatio...

Embodiment 2

[0062] based on Figure 2-Figure 11 , this application provides a preferred partial rendering method on the map in order to achieve the technical effects of improving the work efficiency of the search engine, changing the fineness of information displayed on the map, and improving the accuracy of the map, specifically, as Figure 12 As shown, the method of local rendering on the map includes:

[0063] S1202: Obtain the search area on the map layer, wherein the above search area is determined by the coordinates of the search center point and the search range, the coordinates of the search center point and the search range can be determined by the client according to the user's operation command, and determined by The client transmits to the server; preferably, the above-mentioned search range can be determined in the form of a circle, such as image 3 As shown in the middle shaded part, when the radius of the circle is given, the search range can be determined, and the coordin...

Abstract

The invention provides a method and device for partial rendering on a map. The method for partial rendering on the map comprises the steps that a search region is obtained on a map layer; the map layer is divided into a plurality of map layer partial regions, and intersection regions between the search region and the map layer partial regions are determined; corresponding search results on the determined intersection regions are obtained; the obtained search results are displayed on the map layer. The method and device for partial rendering on the map solves the problem that the processing speed of a search engine is reduced, wherein the problem is caused when a determined search range is too large in the related technology; the method and device for partial rendering on the map improves the working efficiency of the search engine.

Description

technical field [0001] The present application relates to the field of Internet communication, in particular, to a method and device for local rendering on a map. Background technique [0002] In related technologies, if it is necessary to display the search results in a certain area on the map, the image engine multi-point rendering technology is generally used, which includes the following steps: [0003] S1: The client is in figure 1 The central point of the search is determined in the 6 local areas of the map shown, wherein the determination of the central point can be realized by the user inputting the coordinate information of the point, or by the user in the figure 1 The click operation on the map shown is implemented; [0004] S2: The client is at figure 1 The search range is determined according to the center point in the six local areas of the map shown, wherein the search range can be determined by the search radius input by the user and the coordinate informat...
