I have two shapefiles that I'm working with - one of US counties and one of US climate divisions (which are subsets of US states). I would like to match each county to the climate division that it is located in. The only common variable that the two shapefiles contain is "state".
I'm not sure which tool I should use to achieve this. I know I need to match counties to divisions based on geographic coordinates alone, but I have no idea how to do that. Any suggestions would be appreciated!
