Is there a possibility to determine the surface area above the road and the surface of the terrain below the road or between two or more roads? I want to pull the trees down the hill and up the hill to the roads. The price of skidding trees is different so I would like to know what the surface (ha) is above and below the road?
Here is an example, orange is uphill and red is downhill. I think this is solved with a raster calculator
Here is the method, but I do not know how to solve it in ArcGIS Desktop
