This message was sent to Maps-L by Joanne Perry.----------Johnnie -------------------------------------------- A patron is interested in acquiring digitized maps of Mexico, specifically the coastal region from Manzanillo to Puerta Vallarta -- In the Carta de Mexico topografica 1:250,000 this would be sheets E-13-2-5 & E-13-11. They have found that their GPS readings do not match the printed sheet information. Does anyone know any source for this sort of information? Thank you. Joanne M.
