The result of studying of land cover dynamics of river basins of the north-western slope of the Crimean Mountains (Zapadnyy Bulganak, Alma, Kacha, Belbek, Chernaya river basins) using various sets of geodata are presented. The relevance of the work is associated with the constant growth of the transformation of the territory within the river basins under consideration and, as a result, the need to study changes in various types of land cover. The aim of the work is to assess the dynamics of changes in the types of ground cover within the river basins of the north-western slopes of the Crimean Mountains on the basis of open data from various Earth observation programs from space. In the work both traditional research methods (literary-analytical, comparative-geographical, historical, statistical and a number of others) and the latest research methods (geoinformation) are used. The geodata sets of the Land Cover Climate Change Initiative (CCI), GlobeLand30, Esri Land Cover with the greatest time coverage and completely covering the territory of the studied basins are analyzed. During the period from 1992 to 2020, in the river basins of the north-western slopes of the Crimean Mountains, there was a reduction in the area of forest-type land cover and an increase in residential and agricultural types of land cover are founded.

Key words: land cover, Crimea, river basin
