Possibilities of Determining Quantitative and Qualitative Characteristics of Mixed Forest Stands Using Sentinel-1 Imagery

The paper presents studies on using Sentinel-1 imagery data to determine attributes of mixed forest stands. The fieldwork was carried out on the territory of the Kostroma, Vologda, Arkhangelsk regions, the Udmurt Republic. The study revealed that quantitative and qualitative forest characteristics correlate with radar survey parameters; the value of this correlation was identified. The obtained results enabled to make study area zoning the according to the standing volume and forest density.
