The development of exogenous processes on the Earth's surface is a large-scale problem. Due to the development of exogenous processes there are changes in the composition and structure of the earth's crust and its surface. The destruction of streets, houses and public buildings, roads and railways leads to enormous losses. To predict the development of soil degradation, erosion processes on agricultural lands, which lose annual production areas, leads to the formation of a ravine-beam system and reduces the productive amount of land owned by citizens – is a solution. The use of GIS technologies, remote sensing of the Earth and modern programming can partially solve the problem, as it is a rapid identification of areas that have undergone the process of soil degradation and possible prediction of the development of negative phenomena. The use of geodetic software, GIS, information layers of the Public cadastral map can help in the fastest finding of territories, development of the forecast of the further destructive action, development of the corresponding protective methods and their introduction. The areas with manifestations of exogenous processes - soil degradation in agricultural enterprises, where every year the area of highly fertile chernozems is lost, which leads to large losses and landslides in the forest-steppe and steppe settlements of Kharkiv region have been subject of our study. We investigated destructive processes by geodetic measurements in the territories of their manifestations, observations were carried out for 8 years. The development of exogenous processes on the Earth's surface was revealed, which was manifested in landslides in the settlements of the forest-steppe zone and degradation of agricultural lands in the steppe and forest-steppe part of Kharkiv region. The cause of the destruction of the earth's surface were factors independent of human activity. We built 3-D models of development of exogenous processes manifested in soil erosion and growth of the ravine-beam system and determined the degree of erosion after surveying and processing the results of geodetic measurements in the software Digitals. For 8 years, we made changes to the software, surveying the area and building a monitoring line. Also in the settlements on the territory of the two zones, we observed the development of landslides on the streets of the village. Milova and s. Nova Vasylivka, where there is an intensive development of exogenous processes. The use of GIS technologies and remote sensing of the Earth to monitor the development of exogenous processes simplifies the solution.
