I'm using the multiple buffer tool around a series of points for buffer distances 250 m, 500 m and 1000 m around each point. I am then using the tabulate area tool to determine the amount of forest cover from a land cover map within each buffer ring around each point. What I wanted to ensure is that within each buffer zone, such as the 500 m buffer zone that also contains the 250 m buffer zone, is including the amount of forest cover both within the entire 500 m buffer zone area, and is including the forest cover within the embodied 250 m buffer zone as well? I want to make sure it's including the cover in the entire buffer zone for each distance, and isn't excluding what has already been measured in the smaller, overlapping rings.

    If you use the Dissolve_Option="NONE" on the Multi Ring Buffer tool, larger buffers will cover the smaller ones, and any subsequent steps will reflect this. – Barbarossa Jan 29 at 20:36
  • And by cover, you mean will include them e.g. the area of forest cover within smaller buffers inside larger buffers? Thank you! – Jordan Rogan Jan 30 at 20:41
  • I actually have an additional question--I'm now noticing that the tabulate area tool did not include all of the buffers ("zones") in it's analysis, as noted by missing "FID"s in the resulting table. Is there a reason why this would happen and how can I ensure all buffers are included in analysis? Thank you! – Jordan Rogan Jan 30 at 21:45
  • Hi, I'm now having problems where I create a multi-ring buffer with disolve=none, and when I go to tabulate area, it is only given me the info for one buffer and not all three. I'm not sure what is going wrong as this did not happen previously. I need the area within each buffer distance. Please help if you can! – Jordan Rogan Feb 5 at 16:57
