GeoRaster can be used with data from any technology to capture or generate images, such as remote sensing, photogrammetry, and thematic mapping. It can be used in a wide variety of application areas including location-based services, geo-imagery archiving, environmental monitoring and assessment, geological engineering and exploration, natural resource management, defense, emergency response, telecommunications, transportation, and urban planning. In general, raster data covers a wide range of data types, such as digital images, geo-imagery (data collected by satellites), Digital Elevation Models (DEMs), Digital Terrain Models (DTMs), and gridded data (used in raster GIS). The GeoRaster feature in Oracle Spatial manages all of these diverse data types.

Cells or pixels
Spatial domain (footprint)
Spatial, temporal, and band reference information
Cell attributes
Other secondary metadata (such as the date of data...
