Raster Composition/Decomposition
The Compose / Decompose Bands operations allows the user to compose a single raster with bands from different raster and also decompose a raster in separate bands.
The term color composition consists of a combination of 3 satellite spectral bands to form a colorful composition. This combination of bands consists of careful selection, observing if this selection contains the spectral information really desired. It is important also highlight the need to select the color allocation that have the better perception to the human eye, although the contained information is always the same no matter the band combination and color allocation.
