As a response to a lack of an up-to-date nationwide map of land use and land cover for Denmark, Aarhus University and Copenhagen University produced the first version of Basemap in 2011 (Levin et al., 2012). The novelty of the Basemap was that it combined existing thematic geographic information into one land-use/land-cover map for Denmark. Furthermore, Basemap 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, Statistics Denmark decided to finance an updated version of the Basemap for the year 2016. This second version is different in the sense that most of the original input information is included in the final map. I.e. for most input data, the original object IDs are included in the Basemap, ensuring the possibility to link objects and thus land use/land cover information with relevant information from other registers, such as the agriculture registers, the register from the central office of civil registration, the building and housing register and the central business register. For instance, for information derived from agricultural census data Basemap02 includes the possibility to link to other farm and parcel specific information, such as animal husbandry (number of animals), land use management (e.g. application of manure, fertiliser and agro-chemicals) and agro-environmental subsidies. Furthermore, in order to enable comparison over time Basemap02 also includes an updated version for the year 2011, which in terms of applied data and methodologies is consistent with the Basemap V02 for 2016.
