I am trying to color code the states, cities, zips differently based on certain parameters. As the user zooms in they should be able to see the different colors dynamically painted on the maps. Was able to get this at state level as the boundaries required are available. However, struck at a point to get the boundaries for each city and zips of states. (http://www.usnaviguide.com/)
How to get these details? I have the enterprise licence of Google Maps as well. Do I need to procure any other license to get these boundaries so that I can paint them.
I had also gone through geo-coding service but I do not see any methods supporting to output the boundaries of area.
Thanks in Advance
