摘要： 介绍了当前网络型GIS的空间地理数据的传输方法，并在介绍网格GIS特点的基础上分析了其优缺点。由此引入GML(Geography Markup Language)，分析其在网格GIS应用中所特有的优越性，进而探讨了如何在网格GIS中应用GML描述空间地理数据，设计网格GIS通信机制，以解决网格GIS中空间地理数据的存储和传输的问题。

Abstract: This paper introduces the spatial data encoding and transfer methods on the present network-based GIS, analyses the shortcoming of them according to the characteristic of the Grid GIS and subsequently proposes a new methold,that use GML to store and transfer spatial data. Finally it discusses emphatically how to use GML to encode spatial data,and design the communication mechanism of Grid GIS.
