Research on framework of spatial knowledge grid and its implementation technology

GUAN Li ①,WANG Ping ②,LIU Xiang-nan ③(①Institute of Remote Sensing and GIS,Peking University,Beijing 100871,China;②College of Urban and Environment Sciences,Northeast Normal University,Changchun 130024,China;③School of Information Technology,China University of Geosciences,Beijing 100083,China)  
Spatial Knowledge Grid(SKG)is an intelligent,efficient,synergic decision support platform on the basis of Grid GIS infrastructure,spatial data grid and spatial information grid(specialized definition).SKG is characterized by its grid-based service,open technique standards and protocols,intelligent knowledge mining process and integrated architecture.SKG focuses on the management and application of spatial knowledge,including spatial data management and implication,spatial analysis and computation,mapping and remote sensing image processing.The framework of SKG is discussed systematically in this paper.Its implementation flow and key technology with examples are proposed as well.
