I am working on a project to classify land cover for world heritage sites and conservation areas. So far I have been using tabulate intersection for a raster and selecting the conservation area boundary features as the zones.
The issue is that out of the thousands of sites in my region, there are a significant number of overlapping features. Some of these are identical (e.g., a national park is also listed as a world heritage site and the boundaries match perfectly). These sites could be identified using Find Identical and removed. However, many others have significantly modified boundaries. This is not a topology issue, as they are supposed to be different, but also overlap. The issue is simply making sure I do not count the overlapping areas twice.
For the first step, I want to calculate the area (and land cover type) bounded by all features. However, this will double-count some areas. I am looking for the most efficient way to avoid this. Can anyone point me in the right direction on how to, hopefully, semi-automate this?
