Interesting. Reads like the days of less-than-satisfactory base maps. I thought lidar obviated that. Maybe a lidar learning curve of one kind or another. But realizing watch tracks aren't perfect implies good enough contours to realize that -- or maybe trail or other linear endpoints? Being in the forest field checking is what counts. I need to do some!

LIDAR contours are wonderful - the issue is too much detail and trying to figure out which wiggle in the line is what on the ground. I was able to generate a view with 1 foot contours, which when looked at in a macro scale, provides wonderful insights into otherwise not visible old roads, etc.
I've been working with some vegetation projections from the data, with mixed results. It does not do well in dealing with New England "white woods" and differentiating what is really some shade of green.
I've dug out my laser range finder - very helpful in triangulating position in an otherwise bland area, etc.
