Although detailed geographical data are increasingly available, for Denmark, no current nationwide map for land cover and land use exists. Therefore the main aim of the Basemap is to combine existing thematic information for land use and land cover to establish a map for land cover and land use in Denmark. Applied input data include topographic data, data from nature management and nature monitoring and field parcel maps for agricultural land use. Another aim of the Basemap is to ensure full transparency of the developed methodology. This includes detailed descriptions of input data, of the applied pre-processing of input data and of the applied spatial modelling. Existing applications of the Basemap include the development of a land use/land cover map for estimations of effects of climate change; estimations of superior land use and land cover classes and calculations of connectivity between semi-natural habitats and extensive agricultural land use. The transparency of the applied methodology will, in a future perspective, ease the establishment of new versions of the Basemap, based on updated data. Furthermore, spatial modelling and input data can be adapted to alternative purposes and research needs.
