Detailed Description

Spectral Angle Mapper classification strategy.

This algorithm maps the spectral similarity of input raster to the given reference spectra wich can be either laboratory of field spectra. This method assumes that the data have been reduced to apparent reflectance with all dark current and path radiance biases removed.
