Ok, I am sure this has been asked but i cant seem to find the answer. I need to create a "slope analysis" where i determine the slope percentage and classify by usability by a vehicle (1-5% flat to mild, unrestricted, 6-12% mildly restricted, etc) . I am using NED 1/3 data from USGS. I have run the "slope" tool a few times and used the "percent Rise" option and i get weird numbers like 1,219. I thought this option would give me the percentages so I assumed 100% would be the greatest number. I also used the degrees and i but i see that the slope is counted in degrees so percentage is out. And maybe degrees makes more sense for this problem but I am not sure. I am new with this type of analyis and have scoured the help functions and cannot seem to get an answer that helps. Just so you (but you can probably tell) i am an occasional user and a novice. Any help would be greatly appreciated. Thanks.
