Abstract
Computational schemes for forest vegetation identification on airborne hyperspectral images are implemented using the feature of the red edge in the transition region from the chlorophyll absorption band to the maximum spectral reflectance of vegetation and taking into account integral brightness values of the detected spectra. Based on the proposed models, pixel-by-pixel and textural identification of forest vegetation of different types and ages is carried out within a window of a certain size. New possibilities for the identification of the selected types of objects are shown when comparing the obtained results with the data of ground-based forest-taxation surveys of the test area.
