I need to join land slope with a forested ownership shapefile to determine forest residuals based on slope. I have been trying to use the ArcGIS Online "Terrain: Slope in Degrees" raster all day, and can't get anywhere. I've tried to convert the raster values to points, Zonal Statistics, and clip, all setting the bounding polygon in the Environments to hopefully reduce the computation time. Nothing has worked. Any advice on how to get the slope from the raster and joined with my shapefile would be greatly appreciated.
