Hey 3DTrains,
I've recently begun a new route project (yeah, I'm always building different routes) and I decided I would use 30M DEM instead of the normal 10M DEM I always use. However, when in DEMEX, when I try to use the 30M DEM it says "Error opening input DEM file" "Merging DEM data failed".

Did I do something wrong or is there something I am supposed to do to use the 30M DEM?

Thanks,
-Nathan

I just tried it again with a different DEM file an it worked, but not with a couple of other ones. Any idea what is wrong?

Perhaps the original was in the wrong format.

Cheers!
Marc
