| Abstract: | The key technology and practical realization of building up gride spatial index based on file system and databased system have been elaborated. The speads of graphy operating and object inquiring were tested and compared respectively before and after the construction of the index on file system and detabase system. It is proved that building up spatial index was a effective way to improve spatial operating efficienty. |
