I have a roads polyline layer. I have vector-based contour lines. I have converted those contours to a TIN, then created a raster based on that TIN. Now I have my roads and my elevation raster. Now I need a 200ft buffer on the upslope and a 150ft buffer on the downslope. There are many posts regarding this...but nothing simple. I need step by step directions.
I am using ArcGIS 10.4 Advanced with all the bells and whistles.
