Spatial Information Multi-grid and Its Typical Application

A new representation method for spatial data and spatial information-the spatial information multi-grid (SIMG) is proposed. Three potential functions and four aspects of challenges from grid computing environment to geo-spatial information science and technology are pointed. Subsequently the system architecture is introduced. For the applicability of SIMG in national census and decision-making, a SIMGPC scheme(spatial information multi-grid for population census) is designed.
