Geological Survey Maps

I chanced to meet a Mexican geologist with an excellent map book. He said anyone could buy them from Mexico City, but was not specific on how to do so. Defiantly a better map book than those readily available at book stores. It showed rivers and creeks as running or not. It showed what the road conditions were, sand, rock, hard pack, soft, etc. Apparently the Mexican government has accurate and useful maps available, the question is, how to order one?

INEGI is the Mexican organization that publishes maps and other related material. They have offices in Tijuana and Mexicali as well as Mexico City. Do a search and maybe you can find a website for them.

INEGI produces lots of good map products. You can buy from their website or from a number of vendors in US. Most (if not all) of their map products are available on DVD (and in GIS) so you can print/manipulate all you want.

The fed geologic maps used to be online, you can prob find by googling. They were sort of poor quality maps, not very user friendly.

How similar is it to the Baja Almanac map book? It uses Mexican topographic maps as the base...

Here is the 2003 and bigger 2009 Almanacs:



If you haven't seen the 2009... here is part of one map (L.A. Bay area... this one has a couple roads drawn in that were not on the published edition...



The 2003 edition was a bit more detailed with a larger scale... Here is a close up of the area north of Comondu (shows paved, graded and unimproved roads as well as dashed lines for trails (which can be Jeep trails or burro/ foot trails:

I think what we compared was a geological survey map book, a 2003 Baja Almanac, and some paper maps. The survey map was far more informative and accurate than the others. Which is why I want to find one.
