Monguse thanks for the tip. I thought too about this way and measured using google earth etc. However if microdem is scaling to 1/8 a lot of elevation resolution is going in the proces, also when you scale back I think, so we're loosing height details in this way. So I just wonder what's up, you get the same scaling down with microdem as me, but reading the threads I see nobody mentioned this before?

Compare a known distance to pixels/meter on your map

I just exported a map using the 50 and 200 logic and I came out with a 1/8 scale map. SO I had to scale everything 800%
