How are band values represented in a raster?
Raster bands. Some rasters have a single band, or layer (a measure of a single characteristic), of data, while others have multiple bands. Basically, a band is represented by a single matrix of cell values, and a raster with multiple bands contains multiple spatially coincident matrices of cell values representing the same spatial area.
Can a band be used as a composite in ArcGIS?
A combination of any three of the available bands in a multiband raster dataset can be used to create RGB composites. By displaying bands together as RGB composites, often more information is gleaned from the dataset than if you were to work with just one band.
