Method and system for searching interest points based on electronic map

Abstract

An embodiment of the invention provides a method and a system for searching interest points based on an electronic map. The method includes that a mobile terminal sends current position coordinates of the mobile terminal to a geographic information server; the geographic information server searches coordinates of interest points in a preset range of the current position coordinates of the mobile terminal and returns the coordinates of the interest points to the mobile terminal; the mobile terminal calculates a route from the current position coordinates of the mobile terminal to the coordinates of the interest points, and displays the route in the electronic map thereof. By the method and the system, when a user uses the electronic map for searching nearby interest points, position indication of the nearby interest points can be provided, a route for reaching a destination can also be provided, the user can supplement interest point information not recorded yet on the electronic map into the electronic map, and a complete urban interest-point geographic information database can be established in a user contribution mode.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of geographic information, and more specifically, to a method and system for finding points of interest based on an electronic map. Background technique [0002] An electronic map is a digital map, which is a map that is stored and consulted digitally using computer technology. The method of storing information in electronic maps generally uses vector image storage. The scale of the map can be enlarged, reduced or rotated without affecting the display effect. In the early days, bitmap storage was used, and the scale of the map cannot be enlarged or reduced. Modern electronic map software generally uses geographical information system to store and transmit map data. [0003] Point of Interest (POI for short) is a type of content marked on the electronic map. For example, restaurants, hotels, tourist attractions, hospitals, parking lots, public toilets, sales stores and other facili...

Problems solved by technology

[0006] However, the method of searching for POI keywords on electronic maps in the prior art cannot associate geographic location information with the user's location information, that is, it cannot provide users with location-based search POI services

[0007] Moreover, in the geographic information system database used by the electronic map, the information on transportation facilities, public facilities, large shops, and government agencies is relatively rich, while the location information of points of interest, such as public toilets and parking lots, which are often attached to other buildings, is less

[0008] Not only that, the information in the current geographic information system database is massive, and it is difficult to supplement the above information in a macroscopically
