Abstract

The invention discloses a regional content space object indexing method based on a Geohash partition. Method module, the method module comprises a Geohash partition system module, a signal real-time transmission module, a spatial indexing method module and a display system module. The Geohash partition system module is composed of a Geohash algorithm module and a Geohash working system module, andthe Geohash algorithm module is connected with the Geohash working system module. A Geohash algorithm module in the Geohash partition system module is used for laying a foundation for the establishment of space modeling. According to the invention, a spatial index is established by using a two-stage staggered grid division method; spatial data information can be fully utilized; a plurality of contradictions such as unlimited increase of data volume, excessive invalid information, overlong query time and the like caused by over-dense grid division are relieved; therefore, the data retrieval efficiency is greatly improved, the indexing process is simple, convenient and clear, the indexed target is more accurate, errors are avoided, and compared with a traditional method, the method has great superiority.

Description

technical field [0001] The invention belongs to the related technical field of indexing methods and systems, and in particular relates to a region content space object indexing method based on Geohash partitions. Background technique [0002] Spatial index refers to a data structure arranged in a certain order according to the position and shape of spatial objects or a certain spatial relationship between spatial objects, which contains the general information of spatial objects, such as object identification, circumscribing rectangle and pointing space The pointer of the object entity, the spatial data query is the spatial index, which describes the location information of the data stored on the medium and is used to improve the efficiency of the system for data acquisition, also known as the spatial access method. It refers to a data structure arranged in a certain order according to the position and shape of the spatial object or a certain spatial relationship between the...
