I have a large polygon layer representing a few thousand fields, and raster layer with 3 land cover classes. I would like to summarize each field with a single land cover class, and the only tool I can think of to accomplish this is Zonal Statistics.
Problem is, when I try to run Zonal Statistics, I get ERROR 999999, "Too many unique values". What are the limitations on this tool, and is there a better way to perform this summary?
