Currently experimenting with the best way to make a final set of reliably smooth and faithful topographic contours for the Owyhee River geologic Map. First step is to smooth the 1-m dem. I used the spatial analyst\neighborhood\focal statistics function in Arc. Sounds weird, looks great. It was a tip from I. Madin at DOGAMI. Note: The data illustrated in the third figure were used to create the contours in the following post. The point was to smooth the landscape slightly to create a better looking contour set for the final map.
