I have a good map of Santiago, with a good map of the whole country on the reverse side. Published by Mapas Gaar, S.A., in Santo Domingo. They put out a bunch of maps for different parts of the DR. Their website is:
www.dominicanmaps.nav.to according to the back of my map.
Their phone number is (809) 688-8004 or 689-4830. I actually bought mine at the bookstore "Thesaurus" on Ave. Abraham Lincoln in Santo Domingo.
Suerte.
