I'm new to QGIS and in way above my head with the quest at hand. I'm trying to create a 3D map of a Danish city, to this task the Danish municipality has provided a map of the area the so called KORT10 which I would like to import into QGIS, the map consist of four parts which all is DSF files, it should be vector format, but when trying to add vector layer it pops up with an error saying:
"Invalid Data Source C:\Users\.........\KORT10.dsf is not a valid or recognized data source".
I have heard some talk about it being Shapefiles or something like that, but as mentioned this is the very first time using QGIS and GIS in general.
I have uploaded the file from the municipality if what I have just described made absolutely no sense but somebody has an interest in helping me. The CRS system used is "EPSG2583/ETRS89"
I hope somebody has the time and knowledge to help me.
