Patent ID: 8897483

Claim:
A method comprising: obtaining, by an image acquisition system, an image of a plurality of trees in a region; processing, by a computing device, said image to produce a digital representation of said image; analyzing said digital representation to determine, for each tree included in said plurality of trees, a center of a canopy of the tree; producing a digital surface model (DSM) related to said plurality of trees wherein said DSM contains at least some treetops of said plurality of trees and wherein said DSM represents a surface elevation from a predefined reference point; producing a digital terrain model (DTM), said DTM related to a terrain of a region related to said plurality of trees; producing a digital height model (DHM) by subtracting said DTM from said DSM; and determining a height of the at least some of said plurality of trees based on their respective center of a canopy and based on said DHM.
