That looks like it came out pretty good SCM. Is it hard to export? I'd like to do this, but on a topo. It would be helpful to walk a route I'd like to lay out 3/16", then when I'm done, see how many tree's I'd have on it, along with the slope.

***I know, its not that hard to guess 30ft in drop by eye, but I like maps, so...
