Not to sidetrack the discussion (hah!) ... are those the std Karttapullautin 2.5m contours, Jagge? Nice one!
I've recently been using KP for pre-race trail running maps, when I'm not familiar with the course and there's been no published climb values:
1:30k, 10m contours. Yes, yes, the yellow is hideous. But the merge of OpenStreetMap data and colors and Karttapullautin was visually difficult ... so it served its purpose. ;)
