基于PostgreSQL的地理空间数据存储管理方法研究

The Study of Geospatial Data Storage Management Method Based on PostgreSQL

本文基于PostgreSQL及其空间扩展模块PostGIS和空间数据模型理论,分析对比了各类数据库系统模型的特点,研究了PostgreSQL的空间数据存储机制,提出了由PostgreSQL作为数据库,以客户端接口库LIBPQ实现空间数据库连接及PostGIS实现空间数据库表管理的地理空间数据管理办法.

This article is based on PostgreSQL and PostGIS spatial extension and spatial data model theory,it analysis and comparison of the characteristics of various types of database system model,research on spatial data storage mechanism for PostgreSQL,as proposed by the PostgreSQL database to the client interface library LIBPQ spatial database connection and PostGIS spatial database table management of geospatial data management approach.
