As a response to a lack of an up-to-date nationwide map of land use and land cover for Denmark, Aarhus University and the University of Copenhagen produced the first version of Basemap in 2011. The novelty of Basemap was that it combined existing thematic geographic information into one land-use/land-cover map for Denmark. Furthermore, the map was dynamic in the sense that spatial modelling and input data could be adapted to different purposes and research needs. The first version of Basemap has been widely applied in research and advisory projects by research institutions, public agencies, and private companies. In 2016 and 2019, Statistics Denmark financed an updated version of Basemap for the years 2016 (Basemap02) and 2018 (Basemap03). These updated versions were different in the sense that more of the original input information was included in the final map. In 2022, Statistics Denmark financed the fourth version of Basemap. Basemap04 is based on spatial information for the year 2021 and largely follows the methodology of the previous versions, though with minor changes and additions. Furthermore, in order to enable comparison over time, Basemap04 also includes updated versions for the years 2011, 2016, and 2018.
