| Abstract: | As the fundamental data of geospatial information,raster data is widely applied in many special fields,such as remote sense,meteorology,oceanography,medical imaging,geology,airborne and satellite,survey.To find an efficient storage management mechanism for gigantic raster data,including DEM and remote sense image,will be very important to the construction of NSDI and realization of sharing geospatial information.In this paper the storage management of raster data in GIS is analyzed and discussed.Based on the research of physical storage management of raster data,two different storage schemas are obtained in solutions to local files and business database for storage raster data.It also provides a new solution to storage management of gigantic raster data. |
