[Update: January, 2011]

A recent Overland Journal article describes an exciting new option for digital GPS maps for Baja. I haven't tried it yet, but this seems like the way to go for my next Baja trip! GoTrekkers.com is selling a DVD of 1:50,000 topo maps for Baja that works with Memory Map software.

OziExplorer

I've successfully used digital Mexican government "INEGI" maps calibrated to use with OziExplorer software on my little circa-2002 Fujitsu P1120 notebook computer.

I bought these OziExplorer-georeferenced map image files from from a company called BiciMapas, which sells digital scanned-in INEGI maps. I bought all four of their Mexico 1:250,000 map sets (all of Mexico). BiciMapas also sells more detailed (1:50,000) maps.

The OziExplorer software is available from http://www.oziexplorer.com/.

INEGI 1:250,000 vs. Baja Almanac (San Rafael, BC)

Compare my GPS track log (green highlight) overlaid on these two maps of the San Rafael area of Baja California. My track aligns almost perfectly with the first map (INEGI 1:250,000 scale). The second map is from Landon Crumpton's Baja Almanac, which shows many more wonderful details, but unfortunately they're not accurately positioned. You can see how my GPS track overlay reveals gross misalignment problems.

INEGI 1:250,000 vs. 1:50,000 (Erongarícuaro, Michoacán)

If you want street-level details (even individual buildings) for particular areas, the 1:50,000 INEGI maps are worth purchasing.
