Geographic position query method and device

Abstract

The invention provides a geographic position query method and device, and the method comprises the steps: obtaining a query condition of a target location, and obtaining a geographic position code ofan initial geographic area according to the query condition; determining geographic area grid precision corresponding to the geographic position code in the process of querying the target location according to the geographic position code; determining a geographic position query code corresponding to overlapped grid precision of reference grid precision of the reference geographic area grid corresponding to the geographic position code and the geographic area grid precision; and querying a target geographic position code of a target location meeting the query condition in a characteristic geographic area information data set based on the geographic position query code. According to the geographic position query method provided by the invention, the geographic area information of the targetlocation is obtained through query on the premise of effectively controlling the scale of the target location and ensuring the accuracy of geographic position query, so that the query efficiency andaccuracy are improved.

Description

technical field [0001] The present application relates to the technical field of data query, in particular to a geographical location query method and device, computer equipment, and a computer-readable storage medium. Background technique [0002] With the advent of the Internet age, network life and users are getting closer and closer. Although different types of entities (such as restaurants, movie theaters, etc., including but not limited to service businesses) will publish information related to their services on the Internet, people's clothing, food, Living needs such as housing, transportation, entertainment, shopping, etc. still require individuals to manually search through the network or terminal devices to find relevant information. The desired venue and its information. [0003] At present, the geographic location query is based on the Mercator projection, which mainly projects the earth model onto a rectangular map. The unit grid data is generated through the x...

Problems solved by technology

[0004]However, in actual situations, because the earth is a sphere, the area of ​​a single grid is not equal, and it is impossible to clean the data according to the area during data statistics, and The implementation cost is high, and the response loading time when the data is rendered to the map is long. At the same time, this method is limited to geographical location query, and cannot automatically query and filter target places according to user needs. Users still need to search through the Internet by themselves.
