News: I just got topographic base map data for the Guaymas/ San Carlos area.

The source of the data is US NASA - so there are NO restrictions on use or distribution. It was well hidden, took a lot of manipulation, and still needs a bit of cleanup and field verification. The contour interval is 20 meters - although it is currently displayed in feet.

It is in a vector format - so it is easy to add anything to it - trails, landmarks, roads, gates that block access. Currently it is ONLY contours.

Definitely a work in progress. When more complete it can easily be added to Garmin devices, PC/Mac viewers, Android, iPad/iPhone/iTouch, or print sections at specific zoom levels. Lots of others are possible too.
