I have been working with GIS for a few months. I need help with a map request for my boss. I need to display data by county in a state map, However the data was given to me by zip codes. When I display the data for zip codes sometimes overlap county boundaries. How can I display the data for that county by zip code without overlapping the boundaries. Also, how can I just dissolve the zip code inside the county.
Please, I will really appreciate all the help anyone can give me.
Thank you very much,
