GPS systems have become a part of our life. There is GPS in your car, in your phone, and maybe even in your toilet seat.However, most systems in use depend on maps, and how good are the maps.You enter an address or a landmark, and then you follow the instructions to that point.However, its a big planet, and a large part of this planet does not have roads, or has roads which are not yet mapped.So how do you navigate the big bad wild, and live to tell the tale?

Please help.

I didn't find the right solution from the Internet.
