| Abstract: | In order to meet the data management request of massive remote sensing images, the extension approach of spatial raster data management on a native database management system X-Base is studied and implemented. Firstly, the spatial raster data extension architecture based on X-Base is studied. Then, the model of spatial raster data extension is established. Further more, the approach of spatial raster data management based on XML technology is proposed and implemented. After extension, the spatial raster data can be effective managed in X-Base. So the function of the native database management system is enhanced. |
