The Key Technologies Research of Spatial Data Mining Based on the GIS Grid Services

With the increasing of space resources on the Internet, we need a higher demand on the spatial data sharing and knowledge discovery for the heterogeneous distributed data, but the WebGIS only can provide the parts of space resources sharing. In order to solve this problem, in this paper we put forward a solution which used for the spatial data mining and knowledge discovery in the grid environment, and analyzed the software architecture of spatial data mining system based on GIS grid services, and expounded the key technologies of space data mining based on the GIS grid services by the numbers. At the same time we improved the corresponding the solutions on the key technologies.
