This question is related to a previous question I asked as Raster Version of Spatial Join (one to many)
In ArcGIS Desktop 10.1 I used the Tabulate Area tool to crosstabulate values between an overlapping "buffrast" raster (with identities of 1917 different buffer zones) and "RR1.tif" (with land cover codes for each pixel within the 1917 buffer zones). Detailed methods:
Region Group was carried out for RR1.tif with the Add Link option chosen, and the Snap Raster environment enabled for buffrast. Tabulate Area (Spatial Analyst) was used with the following inputs: input raster or feature zone data = buffrast (zone field = ident), input raster or feature class data = RR1.tif (class field = LINK), processing size = 25.
This worked perfectly for most of the points, with total areas adding up to ~70000 for each of the 1917 buffer zones; however I run into problems where two or more buffer zones overlap each other - when this happens ArcMap "doubles up" on the total area of each buffer zone resulting in Areas of ~90000 and up.
How can I run the Tabulate Area tool for such overlapping buffer zones?
