In recent years, spatial database is the focus of research in the field of GIS. SQL Server 2005 and its subsequent versions provide extended module for spatial data, are able to manage mass vector data, combine vector data storage and analysis with their inner cores based on OGC standards, and support T - SQL in an effort to simplify programming. This paper studies the basic function of SQL Server Spatial briefly, and develops a simple GIS application system based on it.%空间数据库是近年来GIS研究领域的热点之一,SQL Server 2005及其后续版本提供了空间数据扩展模块,能管理海量的矢量数据,基于OGC的标准,将矢量数据的存储、分析等功能与其内核结合,并且支持T-SQL,极大地简化了GIS的程序开发.本文简单研究了SQL Server Spatial的基本功能,并且基于它开发了简单的GIS应用系统.
