I've seen other threads ask very similar questions, but I haven't seen one that answers this specifically:
So, I have 4 Total sets of points. 1 set is a set of addresses in Arkansas, the other 3 are different types of toxic waste contamination sites. What I am trying to find out is how to run a query to find and select which addresses are within 20 kilometers of any of those 3 contamination sites.
Does anyone know how I could go about doing that?
