Hi,

As I don't leave in the USA (in fact, I'm from Switzerland, and I can't find free DEM of my country...), I don't know what DEM to download to have a nice valley with high mountains to make a route.

So, if you know one, could you tell me what DEM I have to use, and if possible, the lat/long of the place.

Thank you to help me to find my train heaven....
