In this paper, we propose a method for recognizing the species composition and age classes of mixed forest stands based on joint processing of multispectral and panchromatic satellite images of WorldView-2. The statistical features of Haralik were used to describe the texture features . A previously developed modified decoding method, which belongs to the class of ensemble classification methods was used to perform the trained classification. To assess the effectiveness of the proposed approach, test calculations were made for the joint processing of high-resolution images of the selected area of the Savvatievskoe forestry (Tver region), the results of which were compared with the data of ground forest inventory. A group of natural factors that cause a discrepancy between satellite and ground information was identified when interpreting the calculation results.
