- Create signatures from defined training sites.
- Create pure signatures for use with the linear spectral unmixing option of the UNMIX module.
- Purify training site data.
- Extract fuzzy signatures from defined training sites.
- Display multiple signature graphs for comparison.
- Measure the separability of all possible pairwise combinations of signatures from a specified number of bands using Divergence, Transformed Divergence, Bhattacharyva Distance, or JM (Jeffreys-Matusita) Distance.
- Create a scattergram in band space of two signatures.
