This article is devoted to the study of surface karst manifestations on the territory of inactive salt mines of Solotvyno, Transcarpathian region, Ukraine. The historical development of the salt mine from the moment of the creation of the first mine (the end of the 18th century) to the present is considered. Based on the results of previously published studies, monitoring of karst manifestations from 2010 to 2020 was implemented. The last stage of monitoring in 2021 was the aerial survey of the territory obtained by the Arrow UAV using the Sony QX1 camera. Pix4Dmapper software was used for image processing. The aim of the work is to estimate the scale of destructive geological processes by the method of photogrammetry. During the execution of the work, the methods of processing materials of aerial photography, analysis of developments in the direction of photogrammetry were applied. As a result of the study, the volume-planar characteristics of karst formations on the territory of Solotvyno were calculated using the photogrammetry method. This scientific work is relevant for assessing the scale of the development of degenerative geological processes on the territory of Ukraine, in particular within the Transcarpathian region. The practical significance of the obtained results lies in their application in order to ensure environmental monitoring. The results of the study can be used to predict the impact on economic and infrastructure objects, followed by the development of a plan of specific actions for prevention, localization and work with the consequences of man-made processes in the adjacent territory.

The paper discusses how to apply the information on the density of three-dimensional point cloud, obtained as a result of computer stereo reconstruction of an area, based on aerial images. Images of high objects – particularly walls, treetops, bushes, etc. – in a particular area are used to create a point density map by means of GIS instruments. The information enables redistribution of the weight of cloud points in order to intensify or reduce their impact on the digital model of an area, or orthophotomap. The proposed method has been used to create orthophotomaps based on aerial images obtained from UAS.

The Holocaust - the almost total extermination of European Jews by the Germans during World War II (1939-45) is primarily associated with such German extermination camps as Auschwitz, Bełżec, Majdanek, Sobibór or Treblinka. In addition to these places, Central and Eastern Europe, including territory, within the present Polish borders, is literally dotted with forgotten individual and mass Jewish war graves. These are the graves of Jews who were not sent to the German death camps during the liquidation of the ghettos during Reinhardt’s operation (March 1942 - November 1943), but were murdered during and after the mass extermination. These Jews were buried in nameless graves located in forests, roadside ditches, arable fields, etc. In most cases, their number and exact location are unknown, both for scientists and descendants of victims, although they often exist in the memories of the last living witnesses of the Holocaust and local communities . One of the statutory tasks of the Rabbinical Commission for Jewish cemeteries in Poland is to search for the forgotten graves of Holocaust victims and restore the identity of the murderers who were taken away from them. The Commission, as a religious entity, headed by the Chief Rabbi of Poland, operates in support of the Jewish law - Halacha, whose regulations define the method and methodology of research. Halacha prohibits opening graves and moving the remains of the dead. All investigations specifying the location and size of the graves they must be carried out in a non-invasive manner, without interfering with the soil structure. In this study, the authors present the first results of work on the location of places of execution and mass graves of Jews from World War II, which were carried out using methods respecting the provisions of Jewish law. To locate these places, the following methods are used: the Holocaust witness account, documents from the Institute of National Remembrance, data from laser scanning, GPR measurements, historical and current aerial photographs. The authors will present the methods of their work and the problems they faced during the research.

The Jodłówka region is located in the north-eastern part of the Dynowskie Foothills. The region is characterized by a very high density of landslides and is composed of Cretacoeus-Tertiary sediments of the Skole Nappe. The Inoceramian Beds are the dominant lithologal unit overlain with the Variegated Shales. The present paper focuses on the influence of geological and geomorphological factors upon the landslide occurrence on a local scale. The analysis is based on digital data set including active landslides as well as various types of digital elevation models (DTM), aerial photography and geological maps. These data were combined to compute landslide susceptibility map using index methods.
