Annual soil cover map (JaarBAK), 5 m resolution, 2017

The annual soil cover map (JaarBAK) for Flanders at 5 m resolution is an aggregated version of the original 1 m version of the JaarBAK. It provides the degree of cover for each 5 m cell and is available annually from 2013. The White Paper on Spatial Policy Plan defines 'soil cover' as the surface of which the nature and/or condition of the soil surface has been changed by the application of artificial, (semi-) impermeable materials, as a result of which essential ecosystem functions of the soil are lost (housing, roads, other constructions, etc.). This definition is based on the one used by the European Commission for 'soil sealing': "the destruction or covering of soils by buildings, constructions and layers of completely or partly impermeable artificial material (asphalt, concrete, etc.). It is the most intense form of land take and is essentially an irreversible process". For this map, soil coverage is first predicted by a machine learning model based on the medium-scale winter aerial images of Flanders. This modeled soil cover is then combined with vector information about water, buildings, roads and railways from the Large-Scale Reference Database. For more details about the method used to draw up the Annual BAK, reference is made to the technical report 'Jaarlijkse soil cover map of Flanders' at https://archief.onderzoek.milieu.vlaanderen.be/Onderzoek-3331558.
