I am a little of a mapping enthusiast and I want to make a map of my area with hill rating. I can read a topographic map just fine, but I am aware that there is a system for rating hills in percentile figures (3%, 6%, n%, whatever percent%).
What is the formula to use so I can give a correct rating to my very hilly stomping grounds?
Thanks in advance!!
