Let me explain my project in more detail, I'm gonna do inspect damaged road with a digital elevation map to mark location of damaged area on the road. After some practice of ArcGIS spatial analyst tools, I was able to construct more remarkable models using Hydrology and contour, but still need to observe with my vision. I think the elevation of a road relatively distributed continually flat and some damaged points have a rapid elevation deviation comparing to the neighbor raster. So, if I can model some python tools that is mark the raster with different raster collections, it might be more accurate tools for road inspection. I'll be happy you show me a short path to the answer. Thanks.
