        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.
