The socio-political processes of the early 1990s led to a shift in the development strategy of Sevastopol and the concept of land use in the region. The aim of the article is to assess changes in the territorial structure of land use in Sevastopol from 1987 to 2020 based on multi-temporal satellite data. The main data sources were Landsat-5, -7 satellite images and open-access datasets. Image interpretation was carried out using the QGIS 3.16 geographic information system. To refine land-use types and boundaries, thematic maps, master plans of Sevastopol for different years, the public cadastre, and other available sources were used. The key research methods included geoinformation analysis and synthesis of data, image interpretation, and cartographic techniques. In 1987, 2000, and 2020, the dominant land-use types in the territory of Sevastopol were agricultural, forestry, and residential. In 2000 and 2020, conservation land use also occupied significant areas. Over the study period, the territorial structure of land use saw a decrease in the share of industrial land use (from 80.29 to 47.98%), alongside an increase in communal (from 11.32 to 20.99%) and environmental protection (from 8.39 to 31.03%) land-use categories. The decline in industrial land use was driven by a substantial reduction in forestry areas (from 51.35 to 17.57%). The rise in communal land use resulted from an expansion of residential (from 10.39 to 19.96%) and conservation (from 1.44 to 28.14%) land-use types. Minor growth was observed in cultural-memorial (+0.1%) and agricultural (+0.28%) land use, while more significant changes occurred in special (+1.15%) and reserve (–4.06%) categories. The increase in the number of energy facilities by 2020 allowed this land-use type to be distinguished at the scale of the resulting map. Changes in water management, mining, and recreational land use were negligible.
