Embodiment Construction

[0049] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0050] The embodiment of the present invention aims at the problem in the prior art that information points are only set with one administrative area attribute, so that users sometimes cannot retrieve information points, and provides a method and device for setting information points in an electronic map and retrieving information points in an electronic map methods and devices. By setting multiple administrative area attributes for information points, users can search as many information points as possible, and the search results are more accurate.

[0051] like figure 1 As shown, it is a method for setting information points in an electronic map according to the present invention, including:

Abstract

The invention provides a method for setting and retrieving information points and a device thereof and relates to the electronic map field. The invention is invented to solve the problem that the information points obtained by the existing technology has only one administrative area attribute so that the retrieval result is not complete. The method for retrieving information points comprises the following steps: obtaining an electronic map in which each information point contains at least two administrative area attributes; obtaining the administrative area to which the position of the information point to be retrieved belongs; in the information points of the electronic map, searching any one of at least two administrative area attributes to be the information point of the administrative area to which the position of the information point to be retrieved belongs, generating an information point group; obtaining the identification information of the information point to be retrieved; in the information point group, searching information points conforming to the identification information; treating the searched information points. The retrieval result of the electronic map obtained by the invention can meet the demand of users better.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a method and device for retrieving information points in electronic maps. Background technique [0002] When searching for elements of information points and place names in electronic maps, it is usually done by specifying administrative regions. For example, when a user retrieves a certain information point in Beijing, usually the search engine will first ask the user to select an administrative region before performing a specific search. For example, when a user needs to search for the location of the Forbidden City, he needs to first select Beijing, or more specifically, first select Dongcheng District, and then the retrieval system performs specific retrieval. When searching in this way, the accuracy of retrieval, the relevance of retrieval results, and the retrieval speed are all better. If you search directly without selecting a certain administrative area, the retrieval s...
