Embodiment 1

[0021] The embodiment of the present invention provides a method for realizing POI search, such as figure 1 As shown, the method includes:

[0022] 101. A WMS (Web Map Service, network map service) server receives a first request message sent by a client, where the first request message includes a POI type.

[0023] Wherein, the client may be a browser, or an application program for POI search, which is not limited here. The first request message is sent by the client according to user instructions, and the POI type may be a hotel, restaurant, gas station, etc., which is not limited here.

[0024] 102. The WMS server searches for POI information conforming to the POI type in the first request message, and generates a POI picture according to the POI information, and the POI information is marked on the POI picture.

[0025] 103. The WMS server sends the POI picture to the client, so that the client superimposes the POI picture on a basic map interface to display the POI info...

Embodiment 2

[0029] The embodiment of the present invention provides a method for realizing POI search, such as figure 2 As shown, the method includes:

[0030] 201. The client sends a request message to the base map server to obtain base map information according to the user's instruction, and the request message includes the base map parameters selected by the user, such as the city selected by the user and the field of view.

[0031] Wherein, the basic map server belongs to the network server side and is used to provide basic map information to the client.

[0032] 202. The basic map server receives the request message, determines basic map information corresponding to the basic map parameter in the request message, and returns the basic map information to the client for display.

[0033] Wherein, the basic map information includes basic information within the field of view selected by the user, such as streets, neighborhoods, parks, etc., which is not limited here.

[0034] 203. The...

Embodiment 3

[0057] The embodiment of the present invention provides a device for realizing POI search, which can realize the method of the WMS server in the above method embodiment, such as image 3 As shown, the device includes:

[0058] The first receiving module 301 is configured to receive a first request message sent by a client, where the first request message includes a POI (point of interest) type;

[0059] The processing module 302 is configured to search for POI information conforming to the POI type in the first request message, and generate a POI picture according to the POI information, and the POI information is marked on the POI picture;

[0060] The first sending module 303 is configured to send the POI picture generated by the processing module 302 to the client, so that the client superimposes the POI picture on a basic map interface to display the POI information.

[0061] Specifically, the first request message received by the receiving module 301 also includes field ...

Abstract

The invention discloses a method and device for searching points of interest (POI), which relates to a Web geographic information system and is used for solving the problem of slow response or collapse of a client display interface caused by large amount of POI data. The method for searching points of interest provided by the invention comprises the following steps of: receiving a first request message sent by a client, wherein the first request message comprises a POI type; searching POI information meeting the POI type in the first request message and generating a POI picture according to the POI information, wherein the POI information is marked on the POI picture; and sending the POI picture to the client so that the POI picture is overlapped on a basic map interface to display the POI information by the client. The method and device for searching points of interest disclosed by the invention are suitable for search in sight on a Web map.

Description

technical field [0001] The invention relates to a Web geographic information system, in particular to a method and device for realizing interest point search. Background technique [0002] With the development of network technology, Web-based map search services have greatly facilitated the travel of users. In recent years, with the introduction of Ajax (asynchronous call, that is, requesting server resources without affecting page operations) technology, the performance of web-based map search services has been greatly improved. One of the frequently used services in the Web-based map search service is POI (Point Of Interest, point of interest) search within a field of view. POI search within the field of view refers to searching for a specific type of POI (such as hotels, restaurants, etc.) within the map field of view determined by the user, and marking the search results on the map to present to the user; when the map field of view changes, all The above search results...
