| Abstract: | A logical and physical model for massive raster spatial database is independently designed.The storage in the relational database for massive raster data is implemented.And the Four-tier architecture for massive raster spatial database engine is put forward,which is based on Common Object Request Broker Architecture.Finally,an application case of massive raster spatial database engine is given,which proved the feasibility of the self-designed raster spatial database engine. |
