I am currently using the most up to date version ArcGIS Online. What I would like to do is calculate slope over a certain percentage (35%) within a given polygon. I just need the acreage or square footage of the areas above 35% slope within that polygon. This is for project planning. I found one similar post, but it is 12 years old and I wonder if some of the functions or processes have changed since then. Thank you to any and all who spend any of their time on this.
