The Corine Land Cover (CLC) database is a pan-European vector land cover data set divided into 44 classes (covering 30 classes in Lithuania) according to the type of land cover and its intended use. Currently, five data sets have been developed (for 1990, 2000, 2006, 2012 and 2018) describing the land cover for the year in question and the land cover changes since the previous database. CLC12_LT is a revised and adjusted 2012 land cover database. The refinement of this database took place through the interpretation of the 2012 IRS satellite imagery. The CHA18_LT change database is compiled by entering land cover changes between 2012 and 2017. The creation of this database took place through the interpretation of the 2012-2013 IRS satellite images and the 2017 Sentinel - 2 satellite images. CLC18_LT is created by automatically merging the CLC12_LT and CHA18_LT databases. The smallest mapped object in the database of changes CHA18_LT - for 5 ha area objects, maintaining the minimum 100 m object width.
