This data is the basis for the soil map (newest 2019 version) is available from agricultural ministries Farming GIS (Landbrugs GIS) page https://landbrugsgeodata.fvm.dk/ or the direct link https://landbrugsgeodata.fvm.dk/Download/Jordbunds-%20og%20terraenforhold/Jordbundskort_2019.zip
Geology is available from The Geological Survey of Denmark and Greenland (GEUS) the primary data set is in this connection to the substrata map (Jordartskort) https://dataverse.geus.dk/dataset.xhtml?persistentId=doi:10.22008/FK2/XAFCRS
