I have a DEM across my study area where symbology has been changed to show elevation changes in 100m intervals.
I have a polygon feature class where each polygon delineates a landslide.
My landslide polygons sit atop the DEM. Some of the polygons cross different elevations, e.g. part of the polygon is at 500-600m and the rest at 400-500m. I would like to calculate the proportion of the landslide polygon that lies in each bracket of the DEM. In the example: I would like to know what percentage of the polygon has elevation of 500-600m and what percentage has an elevation of 400-500m? I read a previous question with a similar issue that mentioned using zonal statistics but I haven’t been able to work it out.
I am using ArcMap 10.3.1. I have the 3D Analyst and Spatial Analyst extensions.
