The embodiment of the invention provides a region query method and device, electronic equipment and a readable storage medium, and relates to the technical field of spatial indexing. According to the embodiment of the invention, the dictionary tree comprising the mapping relationship between the character string and the region code is constructed, after the track point data of the target equipment is obtained, the target character string index corresponding to the track point data is determined, and the target region code corresponding to the target character string index can be searched in the dictionary tree according to the target character string index; and according to the target area code, the area to which the target equipment belongs is determined, so that the positioning efficiency of the track is greatly improved, the area to which the track belongs can be quickly and efficiently positioned, and the real-time statistical requirement is met.
Description
technical field [0001] The present invention relates to the technical field of spatial indexing, in particular to an area query method, device, electronic equipment and readable storage medium. Background technique [0002] With the development of positioning technology in the map industry, the amount of trajectory data generated every day has exceeded 10 billion levels, and the maximum amount of trajectory data can be generated above 180,000 per second. At present, the calculation performance efficiency of the existing spatial index is not high, and it cannot calculate a large amount of data in a short period of time, and cannot meet the statistical requirements of real-time sub-regional statistics of the daily activity and trajectory of the equipment. Contents of the invention [0003] Based on this, the embodiments of the present invention provide an area query method, device, electronic equipment, and readable storage medium, which can greatly improve the efficiency of...
