It is a very classic and excellent GPS mapping program developed by Des Newman from Australia in 1996. It is highly customizable, and allows to use and create custom maps for remote locations that are not fully covered by the major map providers like Tele Atlas. Therefore, it is deeply favored by outdoor enthusiasts (especially off-road drivers and adventure travelers).
