Hi Gerd,

why o5m: o5m is much faster to read compared to pbf, and the new algorithm requires a few more reads

As Greenland map hasn't too much data I stayed with pbf ... not really longer splitting.

Specify it in the new parameter problem-file, e.g. --problem-file=./problem_polygons.txt

I added " rel:1279614 # Greenland glacier " to my problem_polygons.txt Now I nearly whole glacier! Amazing improvement! I still missing southern tip of glacier. I will try add some way values to fix it. Many thanks mira
