The main direction of the scientific activity of the department consists in the development and research of stereophotogrammetric methods for solving special problems from various branches of science and national economy, namely:
- Mathematical modeling of photogrammetric monitoring of natural and man-made phenomena and processes. The theoretical principles of determining the quantitative and qualitative indicators of objects, processes and phenomena, their temporal changes based on periodic photogrammetric survey (landslides, floods, inundation, deformation of the Earth's surface, deformation of buildings and engineering structures, mapping for geoinformation systems, etc.) have been developed.
- Application of aerospace surveying methods and photogrammetric technologies in the study of the cultural landscape. In 2007-2009, research was carried out under the international project "Protection of the historical and cultural landscape for the purpose of development of regional characteristics and local economy".
- Creation of geographic information systems for tourist destinations. The theoretical and technological foundations of the creation of tourist GIS using cartographic materials, aerospace images, archival and current descriptive data have been developed. Among the practical developments there are tourist GIS for the territory of the Kingdom of Jordan and the resort town of Skhidnytsia in the Lviv region, three-dimensional modeling of the territories of recreation parks in Lviv (Stryskyi Park, Park-Museum “Shevchenkivskyi Gai”).
- Monitoring of hydrological processes on the basis of aerospace surveying and construction of digital elevation models. A technique for detecting changes in hydrological objects based on aerospace surveying, building digital models of the terrain was developed, and it was tested on the objects of the Dniester, Stryi and Western Bug rivers. A method for monitoring soil leaching processes has been developed.
- Theory and practice of microstereophotogrammetry. The methodological principles of obtaining images of micro-objects using optical and raster microscopes, processing of such images at digital photogrammetric stations to obtain quantitative indicators, graphic display of the relief of micro-surfaces, accumulation of data for statistical analysis of the obtained results (geometry of micro-objects) have been developed.

Important for science and practice results were obtained in studies of the state of the coastline, glaciers, the creation of digital topographic plans, the development of a geoinformation system at the Antarctic station "Akademik Vernadskyi", carried out under the leadership of Hlotov V.M., who repeatedly participated in the work of scientific expeditions organized by research Antarctic Center of the Ministry of Education and Science of Ukraine.
A large volume of unique data, which became the basis for creating cartographic plans and digital models of Antarctic objects was obtained.
