I'm looking forward to my field trip this morning to the study area of this semester's GIS project - Coulee Baton. It's north of Kaplan and Abbeville. I have been downloading the DEMs and contours for the area, trying to get them to look right because the study area comprises 4 quads.
Still studying up on terrain and watershed analysis possibilities in ArcMap. As suspected, those algorithms work much better on very hilly terrain than the flatness of my study area.
