A G-Guide is a set of files compatible with specific products that can be used to transfer route information to a GPS. Each state will be subdivided by areas for individual CDROM releases. Each G-Guide route is composed of navigational waypoints, and track log points for the entire route.
Well... it’s really about getting into and out of some of the most beautiful country in the whole wide world with the aid of an electronic Global Positioning System and data that is loaded into the GPS which acts as a guide.
It’s about saving you time and providing a proven electronic guide that you can depend on.
The routes, waypoints and track log points for all the trails on this site reside in a commercial grade database that is constantly being updated. From this database we can create routes composed of waypoint and track log files for each of the trails.
What we are providing are accurate data about these trails in a format that will save you, the user, many hours of preparation and data entry. Also, we will be enhancing the use of this data to take advantage of all the new technology as it becomes available to the back country explorer.
