利用WFS实现对象关系空间数据库更新

Updating object-relational spatial database by using WFS

空间数据的现势性要求对空间数据及时更新。本文在研究WFS的基础上,提出网络环境下利用WFS进行空间数据更新,使空间数据更新不必依赖特定的平台和操作语言:选择对象关系空间数据库PostgreSQL进行空间数据存储,GeoServer作为网络要素服务器,分别利用uDig和OpenLayers在C/S和B/S环境下进行实现,验证了利用WFS实现对象关系空间数据库更新的可行性。

Spatial Database update is required for the timeliness of spatial data.On the foundation of studying on Web Feature Service（WFS）,this paper proposed using WFS to update spatial data database through the internet,making the update of spatial data not to rely on specific platform and programming language.The experiments were implemented respectively in C/S and B/S environment using uDig and OpenLayers based on open software platforms.It used PostgreSQL as a spatial database and GeoServer as a Web Feature Server.The results proved that it is possible to update spatial database by using WFS.
