I have to calculate a percentage of slope from an Idaho 30m DEM in ArcMap. My work asked me to calculate a 2-8% slope and an >8% slope. I do not want to mess this up so im asking for advice. I have a projection of NAD_83_Idaho_TM (meters) -   I have used the slope tool to calculate percent rise and values are from 0-80. What am i doing wrong here? Any suggestions would be helpful

 

Thank you Kindly
