摘要
随着GML规范的不断完善及GIS软件供应商的广泛支持,GML已经成为事实上的空间数据编码、传输、存储、发布的国际标准,越来越多的空间数据开始以GML格式存储。如何有效地存储管理GML空间数据,已经成为GIS研究的热点问题。本文研究利用Oracle数据库对GML数据进行存储管理,对其存储和查询进行分析比较。利用Oracle数据库存储GML空间数据的研究,将有利于推动GIS之间的数据共享及WebGIS的发展。
With the development of GML specification and its broad supporting by many GIS software vendors, GML has become the defaeto international standard for spatial data encoding, transmitting, storing and publishing. More and more spatial data has being stored in GML format. Issues as how to manage the spatial data in GML format efficiently have been becoming the hot ones in GIS. This article tries to store GML data in Oracle DBMS. The storage and query of GML data were analyzed and compared. The research on GML data storage in oracle will promote data share between GIS and Web GIS development.
