I have a layer of many polygons indicating water area, scattered everywhere. Some of them are very close to another.
I want to know what's the slop around the water sites. So I already have a layer of slope all across the whole area.
I intended to generate 50m, 100, 150 buffer, then use the tool "Zonal statistic as table" to give me the slope around those waters' data. But I found some polygons are located in the buffer area of another polygon. As you may guess, slope data on the water site is 0. If I go to zonal analysis directly I will get a wrong answer about the average slope.
So I want to eliminate the water area located in the buffer zone.
How can I do that using ArcGIS Desktop 10.3?
