摘要
针对传统GIS存在的数据共享困难,以及出于简化GIS开发过程的考虑,文章介绍了WebService和ASP.NET的基本结构和概念,提出了基于WebService和ASP.NET的GIS架构,该架构可以通过ADO.NET访问异构分布数据源,在WebService中封装数据处理模块,对对外提供服务接口,系统具有良好的可扩展性,便于升级维护。
Aiming at the difficulty of data share existing in traditional GIS and predigesting the process of GIS developing,the basic concept and architecture of Web Service and ASP.NET were introduced,a new GIS architecture based on Web Service and ASP.NET was put forward in this paper.The GIS architecture can access the distributed and heterogeneous data source using ADO.net,seal the data processing module in Web Service and provide service interfaces,the system has good expansibility and is easy to maintain and upgrade.
