基于PostGIS的异构地理空间数据组织与应用开发

摘要

PostGIS is a spatial extension of PostgreSQL which is an open source relational database system.This paper analyzes sever-al existing modes of heterogeneous spatial data which currently works in the field of geographic information, proposes an integrated ap-plication solution of multi-source spatial data for PostGIS database combining the method of PostGIS spatial data organization, and fi-nally conducts a visual application development practice in environment of .Net development.%PostGIS是开源关系型数据库系统PostgreSQL的空间扩展。本文分析了目前在地理信息工程领域的异构地理空间数据几种存在形式，结合PostGIS的空间数据组织方法，提出了针对PostGIS数据库的多源空间数据的集成应用方案，并在．Net开发环境中进行了可视化应用开发实践。
