Is Geo-services Ready? ----on Generalized and Specialized Spatial Information Grid
نویسنده
چکیده
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 GPS, 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 wireand 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.
