基于PostGIS的空间数据库设计与实现

PostGIS是开源对象关系型数据库系统PostgreSQL的扩展。本文基于PostGIS空间数据库,实现对矢量地图数据存储、管理和操作。搭建PostGIS空间数据库,以中国矢量地图数据为例,实现PostGIS数据库对矢量地图数据管理。

PostGIS is an extension of PostgreSQL,an open source relational database system.Based on PostGIS spatial database,this paper realizes the storage,management and operation of vector map data.Build the PostGIS spatial database,take the Vector map data of China as an example,realize the vector map data management of the PostGIS database.
