The relevance of the work is caused by the need to track the changes in natural environment to anthropogenic impacts, especially in residential areas, and ensure proper valuation of land. The main aim of the studyis substantiation of conceptual and technological foundations for creation of monitoring system of the land and the dynamics of the anthropogenic impact on the territory for mapping and cadastral valuation. The methods: interpretation of remote sensing data; route field observations on the reference test sites; method of landscape analysis; method of systemic mapping; analysis of thematic maps of different scale; cartometrics research based on geoinformation technol ogies. The results. The paper introducestheresults of studying the nature of the changes of anthropogenic load on the landscapes of Sakhalin on the basis of cartometric analysis of forest-covered areas, logging, and residential areas by maps in scale 1:100000, published in the mid 1980+s and by space images transmitted from scanner Landsat-7, Landsat-8 with a resolution of 15-30 m. The authors identified the trends to change in the area of different types of landscapes and settlements in the island territory. Landscapes of the south of Sakhalin was subjected to change during the development of forest management, mining, water management. Valuable industrial forests in accessible areas are essentially heavily modified. However, forest management is possible under condition of ensuring environmental safety and reproduction of renewable forest resources in the region. Residential load in the South-Eastern part of Sakhalin is relatively low. The increase in the area of Yuzhno-Sakhalinsk is not due to multi-storey construction, but due to individual housing construction. The capabilities of ArcGIS allow assessing the growth of the urban area on individual areas of the city. Summary. The authors revealed that for the time between the topographic and space shooting, the residential load on plain type landscapes has increased almost throughout, and ...
