ArcGIS Workflow Manager Within a GIS, the uses of raster data fall under four main categories: Rasters as basemaps A common use of raster data in a GIS is as a background display for other feature layers.

Overall, quantitative analysis is intuitive with discrete or continuous rasters. Taking apart a raster stack or opening some proprietary formats can require special techniques or outside software. In multi-band rasters, each band can be a range of wavelengths, for example the red/green/blue bands of an RGB composite image. A single band raster holds one value per cell. 2008-09-22 · A common use of raster data in a GIS is as a background display for other feature layers. For example, orthophotographs displayed underneath other layers provide the map user with confidence that map layers are spatially aligned and represent real objects, as well as representing additional information.
