Abstract: Solotvyno is an urban-type village in the Tyachiv district of the Zakarpattia region, located in the Marmar basin on the right bank of the Tisza. It is known as a resort of local importance, which functions in the conditions of the development of negative geological manifestations [Stella Shekhunova, 2020]. Resort and recreation activities on the territory of the settlement also extend to areas that require constant control and can pose a potential threat to people and cause the destruction of infrastructure. When carrying out studies of territories in general and its recreational infrastructure in particular [V. Novikova. 2016] often use remotely received information about the terrain such as space and aerial photographs. This applies both to the organization of monitoring studies [Yakimchuk et al., 2021] and to the assessment of the manifestation of threatening phenomena [Geomatika..., 2016; Kravchuk and Dorozhynskyi, 2018]. Modeling the state of recreational areas involves the use of geoinformation technologies to create cartographic and statistical documents [Dorozhynska O.O., 2006]. The methods of classification, analysis, and comparative method were used when performing the master’s qualification work. The methods of cartography, photogrammetry, space sensing of the Earth and GIS technology were used in the implementation of experimental research. The work was performed in QGIS software. The study of the territory of the village of Solotvino at the municipal level (42 km2) was carried out with the help of GIS QGIS according to the data of the ESA WorldCover 10 m geoportal [ESA, 2017]. Analysis of land cover changes for 2020-2021 showed that the landscape here is dynamically changing. In particular, the intensification of agriculture, an increase in built-up and artificially covered territory, and a significant decrease in meadows and pastures were revealed. These figures indicate a fairly active anthropogenic transformation of the territory during one calendar year. The zone of interest at the local level of the study is the recreational area in the southern part of Lake Kunigunda, where economic activity and the provision of recreational services began relatively recently. According to research results [Stella Shekhunova, 2020], the area under study is located in the zone of manifestations of potentially dangerous processes: subsidence, karst-sufosis collapses, surface shifts, microslides, erosion, etc. (technogenically and anthropogenically disturbed territory of historical mining activities). Analysis of UAV aerial photographs of 2017 and 2021 shows high recreational activity in this area. A resort and recreation infrastructure is being created here, represented mostly by temporary structures, arrangement of parking lots, construction of small architectural forms. The object of the study is the recreational infrastructure on the territory of the village of Solotvyno, Zakarpattia region. The subject of research is the methodology of municipal and local monitoring of territories using modern products for the processing of space images and materials of periodic images from unmanned aerial vehicles (UAVs). The purpose of the work is to develop a methodology for evaluating changes in the spatial development of the Solotvino resort in recent years on the basis of geo-informational models created from the materials of space and UAV aerial photography. This scientific work is relevant and has an applied application. To assess the development of resort areas, it is proposed to use materials from space photographs, and at the local level - periodic aerial photographs from UAVs. Keywords: recreational infrastructure, monitoring of recreational areas, analysis of terrain changes, geo-information technologies, archival materials of UAV aerial photography.
