I have been trying to create slope and Hillshade rasters from a DEM raster, which is in UTM11N. I tried different ratios (vertical to horizontal) but everything is in meters so it should work fine. I get these stepping slopes going from 0˚ to 50˚ and back rather than a continuous slope. I was wondering if it was normal to have these lines rather than a continuous slope. If not what can I do to avoid this?
