I am looking for a method to calculate the majority of one polygon file (a map of ecoregions) in a sampling grid (fishnet) in ArcGIS. The purpose is to assign each sampling grid (fishnet) to an ecoregion. The determining factor will be the majority of area.
I had a decent method of working out the problem using Tabulate Area tool, but the numbers were almost all identical indicating something weird was going on. I didn't trust it. I was also playing around with the intersect tool then dissolve, but couldn't find a way keep the attribute data I needed (in this case, the ecoregion I want to label).
Problem: Label each sampling grid by the majority area of ecoregion within the sampling grid.
Can someone help me out?
