A map retrieval method and system thereof

Abstract

The invention provides a map retrieval method and a map retrieval system. The method comprises the following steps of A, obtaining the click operation input by a user on a current pattern map, confirming the click site coordinate corresponding to the click operation, and confirming the administrative region range corresponding to the click site coordinate in the current pattern map according to the click site coordinate; B, finding map data matched with the confirmed administrative region range by using a preset administrative region range map database; and C, calling the found map data, and displaying the found map data in a pattern map form. The map retrieval method and the map retrieval system have the advantages that the display is performed by using the administrative region as the region unit; obvious boundaries are formed among administrative regions, so that the user can fast lock the geographical range of the administrative region to be found; relevant information in the administrative region can be known in time; and convenience is brought for the position positioning and information finding of the user.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a map retrieval method and system based on a hierarchical administrative region simulation map. Background technique [0002] Electronic maps have been widely used at present. More and more people know their current location information and surrounding geographic information through online network maps. The current map retrieval system is mainly based on the geographic information selected by users and uses the geographic information Display a regular-shaped geographical range containing the geographical information at the center according to a predetermined display magnification. For example, when the user selects a geographically limited area as a search condition, the display results of the existing map retrieval system usually include not only the Geographically restricted areas also include their surrounding areas, and there is no clear boundary between the tw...
