1. A computer-implemented method, comprising: (a) receiving an image of a portion of the Earth; (b) detecting one or more tree crowns in the image; (c) for each of the one or more tree crowns: (i) representing the respective tree crown as a color, texture and entropy histogram; (ii) reducing the dimensionality of the color, texture and entropy histogram to produce a reduced dimensionality color, texture, and entropy histogram; (d) clustering, into one or more clusters, similar reduced dimensionality color, texture and entropy histograms for the one or more tree crowns; and (e) assigning each cluster to a tree species to match each detected tree crown to a corresponding tree species.
