The Middle Rio Grande Bosque is a stronghold of wilderness and diversity set in the midst of the Albuquerque metropolitan area and its environs. A method for classifying trees based on sUAS data would be useful for monitoring species diversity within that extent. Such a spectral library is specific to the extent where it was developed. My research will determine the geographical limits to the utility of a such a spectral library by testing it in the Bosque del Apache National Wildlife Refuge, roughly 160 kilometers downstream.
