* Storing separate but equal models for land, snow, desert, and land/desert mix makes easier the generation of a scanner model index from cloud and geotype information.
+ These are linear composit models (50-50 for each constituent), not independent models, which function as separate scene types for scanner processing.
++ Snow geotypes must be either clear or overcast.
