摘　　要：地质空间数据在线服务系统是以MapGis-IMS SEE为基础平台,借助VS 2005、SQL Server 2005等工具开发的应用系统。该系统包含表示层、业务逻辑层、数据访问层的三层体系架构。它综合运用JavaScript、Ajax、VML、矢量数据栅格化、CSS、XML等关键技术,实现了空间数据的在线缩放浏览、动态切换、图层叠加、属性查询、在线订购、资料目录检索等重要功能,从根本上解决了地质资料空间数据服务方式单一的问题。With MapGis-IMS SEE for the foundation terrace, and a forerunner of the development tool Microsoft Visual Studio 2005 and Microsoft SQL Server 2005, combined with the key techniques of website developing, geology spatial data on-line service system carried out some important functions. And they include the space data of on-line zoom to browse, the dynamic state cut over, the diagram layer add, the attribute search, on-line order, the data catalogue index etc. And this system is referred to the three layer system structure which is recommended by Microsoft. The structure is constituted by the express layer, the business logic layer, the data interview layer. Finally, this system resolved the problem that geology diagram space data service method is single and no variety.
