Hiking trails are navigable on Smart Phones, and are overlaid on both Smart Phone GPS and Garmin GPS units. Garmin users will be able to follow a trail and see where they are on it, but not be able to navigate from place to place. Smart Phone users will be able to pick a trail to navigate across other trails to, or to navigate to included Points of Interest along the trails. The POIs will be at the trail, to make them navigable, instead of at their exact location.
