System Design of Grid GIS and Its Application on Remote Sensing Image Processing
网格GIS系统设计及其在遥感图像处理上的应用

With the development of computer science and its relative subjects,Internet technology has entered a period of high-speed development,and geo-information science has developed itself with the development of computer science and Remote Sensing (RS).But with the data gained becoming larger and larger,many data can't be fully used for the difficulty of data duplicating and data storage.So how to develop Internet to fill the need of colossal data sharing becomes a difficult problem for many computer experts to solve,the idea of grid computing then appears.This paper centers on grid computing and its application on GIS,after analyzing the common problem and the development of grid GIS,this paper points out that the distributing architecture which is based on GML Internet language and Web Services technique and middleware is a main developing direction of current GIS software and the best way to solve the problem it faces,then its implementation process is discussed.
