I have 2 data sources in excel files. One has city, state and zip at property level and the other has a list of longitude and latitude points at county level. At the moment I have 2 separate symbol maps created. Is there a way to overlay one map to the other if there are no data points in common other than the map results? I tried an outer join to union the data sources but that does not work. I can't use an inner or left join since there are no common data points to link. Any assistance would be appreciated.
