Until 2014 the aerial photography was carried out using analogue Leica RC30 camera. In 2014 was purchased a digital scanner Leica ADS100, which provides images of very high spatial resolution in four bands: blue, green, red and near-infrared. In connection with the transition to the new equipment it is necessary to study the variability of spectral lumi nance characteristics of the main tree species and on the resulting images. The variability of change of spectral luminance characteristics of a shaded and illuminated parts of crowns of major tree species in images of very high resolution are investigated. Regularities of the change of the average value of th e spectral brightness of the tree species depending on age class are described. The analysis of separability of the classes crowns is given, the classification of images of controlled and uncontrolled methods and subsequent evaluation of their accuracy was performed.
