It quickly guides you through ENVI’s end-to-end hyperspectral tools (EFFORT → MNF → PPI → n-D Visualization → Spectral Mapping → GLT georeferencing) to produce image-derived endmember spectra and image maps. For more detail and step-by-step procedures on performing a complete hyperspectral analysis, refer to the series of ENVI hyperspectral tutorials (introductory through advanced) before attempting this tutorial, and refer to ENVI Help when necessary.
