i.class -

i.class performs the first pass in the GRASS two-pass supervised image classification process. The GRASS program i.maxlik executes the second pass. Bothe must be run to generate a classified map in GRASS raster format.

i.class generates spectral signatures for an image by allowing the user to outline regions of interest. The resulting signature file can be used as input for i.maxlik or as a seed signature file for i.cluster.
