Abstract
In this work we represent the possibility of using satellite images of medium spatial resolution for thematic interpretation of meadow ecosystems located in the flood plain of the Northern Dvina river. We have used multidimensional scaling to study the differences in spectral characteristics. Classes such as arable land, water, mineral soils, forests and swamps are most well-classified. However, the meadow ecosystems overlap with reed beds according to spectral characteristics. Therefore, for more accurate identification of meadows, it is recommended to use different vegetative indices, for example NDVI and Cl Green. As a result of the research, a map of the distribution of meadow ecosystems was created using GIS.
