I try to make maps of the different administration units in Denmark but have problems with finding the correct CRS.
I downloaded GeoJSON files from this repository.
When I import one of those to QGIS, it looks like this
But I expected it to look more like this. (I mean the general form, not the colours or borders.)
I did some research which CRS would be best for Denmark, and in this list, I found out, that "ETRS_1989_DKTM1" should be fine. But unfortunately, I still don't get the result I want.
What CRS should I use? Or is it something else that I did wrong?
