I'm new to ArcGIS so sorry if this seems trivial at all.
I'm trying to find the slope angle of roofs. I have the DSM and DTM of my area and then drawn polygons over each rooftop. I have used zonal statistics which has found the Standard deviation of the slope but i'm not sure how to convert this to a degree/percentage value. I also feel like there must be an easier way of doing this that i dont know about.
My overall goal is trying to find suitable roofs to convert to a green roof. so if anyone knows of any completely different ways to get all the data and outputs id need for that then that would be amazing .
Any help would be greatly appreciated,
