Summary/Abstract: The study of land cover changes is very important to have proper planning and utilization of natural resources and their management. The aim of this paper is to classify the study area, for two different time periods and to analyses the change detection using free-of-charge Sentinel-1 data. For this case study, dual-polarization (VV+VH) Interferometric Wide swath mode (IW) data collected on August 16th 2017 and October 11st 2017, over South-Est of Romania, were used. Pre-processing and processing were conducted using ESA Sentinel-1 toolbox (S1TBX) in the Sentinel Application Platform provided by ESA. Data have been calibrated, terrain corrected, and classified using supervised classification. The training and test data have been collected from Sentinel- 2 images.
