I would like to give some hints how to get 1m elevation data for Norway.
The data source is hoydedata no.
The exact procedure is shown here:
Google for "transdem Norwegian 1m DEM"
Clich the world globe in the upper right and select "English"
These are the correct settings:
Please be aware, that even small areas generate a huge amount of data!
The program Transdem is not needed. The conversion will be done with QGIS.

I dragged and dropped the downloaded TIFF files into the open QGIS ,
and merged them with "raster / other/ melt:
and saved them as EPGS:4326, WGS 84. This converts them to a AFS2 compatible format.
Generate the TFW file too.
Please take special notice of the negative sign of the vertical layer resolution. ALWAYS (-).
After this, geoconvert them to level 12 13 14 also 6,7,9 and 10 if the position is north of 60°N.
6..9 will need to allow masking, as this is a bigger area then your tiff files might cover.
With these data you will even be able to see smaller sand hills...
