GeoHash coding method for one-dimensionalizing geographic spatial data for NoSQL database
The invention discloses a GeoHash coding method for one-dimensionalizing geographic spatial data for an NoSQL database. The method comprises the steps that a code mapping table from standard GeoHash code to balance GeoHash code is generated according to historical statistics of spatial distribution;...

| description | The invention discloses a GeoHash coding method for one-dimensionalizing geographic spatial data for an NoSQL database. The method comprises the steps that a code mapping table from standard GeoHash code to balance GeoHash code is generated according to historical statistics of spatial distribution; spatial data is stored in the NoSQL database by taking the balance GeoHash code as a keyword; when spatial query is conducted, the spacial range is converted into a series of GeoHash value intervals on a balance GeoHash code space, and one Scan query supported by the NoSQL database is generated for each GeoHash value interval. Compared with the standard GeoHash code, geographic spatial point elements are stored in NoSQL databases such as HBase by taking the balance GeoHash code as the keyword, and by means of the spacial range query method, higher spatial query efficiency and shorter query response time can be achieved.
本发明公开了种面向NoSQL数据库的地理空间数据维化GeoHash编码方法，首先依据空间分布的历史统计数据生成标准GeoHash编码到平衡GeoHash编码的编码映射表；然后以平衡GeoHa |
