The purpose of this paper was to perform an analysis in order to detect the change in land cover in Timis County. Timis is the largest county in Romania in terms of land area, occupying 8.696,7 km2, respectively 3.65% of the country’s surface. It is intersected by the parallel of 46 Lat. N, by the meridian of 21 Long. E and 22 Long. E. For this to be done, the existing database at European level was used, following IMAGE and CORINE Land Cover (CLC) 2000 project managed jointly by the European Environment Agency in Ispra, Italy and downloaded from the portal www.landcopernicus.eu. The database Corine Land Cover includes 29 countries from Europe, covering an area of approximately 4.5 km2, at a scale of 1:100.000. This research wants to analyse based on Geomatic Technologies, the land cover change detection in Timis County, based on the open-source data CLC. For analysis, four groups were taken from the data set, Artificial Surface (AS), Agricultural Areas (AA), Forest and Seminatural Areas (FSA) and Wetlands and Water Bodies (WWB), whose evolution was analysed during the period 1990 to 2018. Data manipulation and processing were performed with specialized programs, such as: ArcGIS v. 10.3, Microsoft Excel and Past. In this study was used GIS data: raster and vector, Vector Data sets CLC 2990 – 2018, Limits of administrative units, countries, territorial administrative units, localities – in vector format, Statistical data in database format, Base maps in raster format and a SRTM model – raster format. Timis county, according to Land cover, it is a county that has mainly agricultural lands in its component. It shows that most of the land in Timis county (51.4% and 32.9%) has an elevation between 0-100m, respectively 100-200, and most of the land covers characteristic of this range, is specfic up of Agricultural areas 46.1%, respectively 32.9%. In the year 2018, the percentage of the agricultural area in Timis County was 78.17%, which represented 45557.69 ha.
