I have a raster file that I clipped to a 5oom buffer - see picture. In each clip the are multiple land uses. I would like the dominant land use in each clip for each zone in a table. I have used Tabulate Area tool but that just gives each land use area for each clip and I only want the dominant land use in the buffer area.

Without any data to experiment with, I wonder if the Zonal Statistics As Table GP tool would do the job here.  Are you able to share a sample of the data to experiment with?

Zonal Statistics as Table should work. Choose "MAJORITY" as the statistics type.

Please ensure no record is selected in the attribute table of the buffer layer.

Here is what I get executing Zonal Statistics as Table on your dataset.

Thank you for your reply. I tried that and it looks promising but could not get it to work. I'm new to this so I am not sure what sample data to provide.

I have used Tabulate Area tool but that just gives each land use area for each clip and I only want the dominant land use in the buffer area. 

So can't you just sort on what ever field got populated by the Tabulate Area tool and find the maximum?

 

That should just about do it....

Yes, but that does not preserve the category that the maximum came from which is what I am really after. I could do it for each line of data manually but I have hundreds. Thank you for your help and congrats on imminent retirement:)

This did finally work - thank you so much. One more quick thing - is it possible to know not just the majority category but the area of that majority (the sum of the area in the majority of a circle/buffer)?

Thanks again. I did try but the output table only has one line with the majority identified. And the area is the area of the buffer (circle 500m radius) not the area of the majority. Regardless it is only for one ORIG_FID see screenshot. I really appreciate your help.
