Slough Creek update: I can no longer say the map is entirely a desk mapping project. I visited the area on my way home from Ft Leavenworth and looked around a bit.
I've added the hiking trail based on a GPS track.
I noted that I've been over drawing some features from the lidar data. In particular, I've drawn some streams that should probably be ditches and some ditches that should be removed. The features show up clearly in the lidar, but much less clearly in the terrain.
The lidar vegetation for runnability is really good.
I confirmed that a couple of the roads are blocked off. I thought I could see locked gates on the air photo, but wasn't sure. Now I'm sure.
There are areas of rocky ground that I'll need to add. I wonder if they show up in some way in the lidar? I'll look. If not, I may sketch the areas in using the old 1983 map.
