Abstract

Early results from automatic tree species discrimination, using the Z/I DMC digital air photo camera are reported. The position of single trees is identified using template matching techniques and spectral information is extracted from the sunlit part of each detected tree crown. The imagery was acquired in mid October 2003 for a test site in western Sweden. A discriminant analysis based on canopy colour, yielded 88.7 % overall accuracy when discriminating between Scots pine (Pinus sylvestris), Norway spruce (Picea abies) and deciduous trees. The promising results are of great practical interest since the Swedish National Land Survey recently has acquired a Z/I DMC camera
