The interpretation of aerial photographs in Republic of Moldova has been carried out since the 70s. Today in Institute of Ecology and Geography (State University of Moldova) remote sensing satellite images are proving useful in three scientific research areas: Landscape geography, Geomorphology and Ecopedology, Climatology and Environmental Risks. Helpful problem-solving techniques of satelite imagery processing include: land cover classification, thermal modelling and digital elevation model generation (DEM). The data gathered by Sentinel-2 satellites were used to detect categories of land and to create DEM.The following programs were used for data management: SNAP, ArcGIS Sofware, Erdas Imagine and QGIS. Results obtained through the above mentioned methods allows researchers to thoroughly investigate land use and cover change (LUCC), to detect exogenous processes manifestations, to understand land-use impacts on landscape stability and to study climate change. These studies are very important, because there is a significant demand for regular studies of hazardous exogenous processes in Republic of Moldova.The study aims to describe and to analyze the algorithms of Remote sensing data processing in laboratories of Institute and to propose new research directions using high resolution satellite imagery. For example, satellite images can be used to determine shifts in ecological activity, like a swampland drying up, lakebed flooding, seasonal variation of water storage in river basins or river bed erosion. Also, such advanced approaches can be becomed of the basis for establishing an effective mechanism for monitoring of statewide exogenous geological processes. It is concluded that Satellites and other remote sensing tools offer new ways to study ecosystems. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately. The technological prowess of Copernicus, especially in terms of availability and accessibility, has made Copernicus the largest space data provider in the world.
