The map does show the Baltimore area but that city has no buildings that look even close to the Polis one. Odds are the grounders called it Polis because it was part of its original name so Polis is most likely modeled after Minneapolis and that round building looks a lot like a weathered version of that cities round skyscraper. Also the forests in the show look an awful lot like north woods. Another candidate is Indianapolis it has a similar building too but not as good a fit.
