The SNORTEX measurement project organised by the Finnish Meteorological Institute used helicopters to manually collect extensive photo image in the Sodankylä area during the winters from 2008 to 2010. Using these high resolution images, the University of Eastern Finland and the Finnish Meteorological Institute have now been able, using a new imaging method, to automatically identify the relative quantities of the three most important tree species: pine, spruce and birch. The level of classification precision was 81.9%.
