Hi,
I am trying to create a wetland extent raster for a very large wetland. I have a DEM of the area, and I would like to create a sloping (instead of horizontal) planar surface (which is parallel to the longitudinal slope of the river on which the wetland is located) so that it can cut through the DEM in order to create a wetland extent. Is there a way to create a sloping planar surface that is parallel to the slope of the river? Thank you!
