Conventional habitat mapping and inventorying, especially in hostile areas, is onerous. Generating this important research and conservation tool could be accomplished quite easily, especially for easily distinguishable plant species in open terrain such as savannah palms or the spectacular Andean Puya raimondii, with the development of suitable spacial or spectral scanning algorithms. Any expertise or ideas in this area would be very welcome. (This question has also been posted under Agricultural Science.)
