摘要：After the setup of spatial data infrastructure (SDI) and national information infrastructure (NII) in many countries geo-services become one of the most important and attractive tasks. With the integration of GP S, GIS and Remote Sensing (RS) we can principally answer any geo-spatial related question: when and where what object has which changes. An intelligent Geo-service agent would provide the end-uses with the most necessary information in shortest time and lowest cost. Unfortunately it is still a long way to reach such demand. The central component in such Geo-Services is the integration of spatial information system with computer grid via wire- and wireless communication networks. This paper will mainly discuss the grid technology and its integration with spatial information technology, expounding potential problems arisen and possible resolutions. A novel categorizing of information grid in the context of geo-spatial information is proposed: generalized and specialized spatial information grid
