The European Environment Agency (EEA) CORINE dataset on land use in Europe has been updated to the latest version 20, finalised in June 2019. With the upgrade of the data set from version 18.5 to version 20, the data has been changed from 2012 (CLC2012) to the data from 2018 (CLC2018). As expected, the 6-year cycle will result in some changes to the data set.
Further information on the data can be found, for example, in the "CLC2018 Technical Guideline" of the EEA (Service Contract No 3436/R0-Copernicus/EEA.56665).
