本文从应用整合和数据整合入手，提出了在分布式计算平台上以空间信息显示，服务，获取，存储为基础的层次化GIS软件框架，以便提供数据分析，共享，知识发现不同水平的空间信息服务。

With the fast development of Internet, it is important for GIS to make it more open. The meaning of conformity for GIS is to change software of GIS in system architecture and data access in order to accord with the requirement of spatial data sharing, integrating and knowledge discovering. This paper puts forward a hierarchy for GIS based on distribute computing platform, which includes four layers those are spatial information display, spatial information service, spatial information access, spatial information storage from top to bottom. Every layer is make up of several functional components. The down layer provides service for up layer. To manage spatial and other information universally, this paper also discusses how to put spatial information into large commercial database which supports geometry type or not directly. Based on the idea of conformity for GIS and knowledge disvovery, this paper also presents an example called GeoBeans.
