GPS enabled devices like the Garmin Monterra GPS Navigator with US Topo Maps, lets you plan your next route using a third party app called “Base Camp” that lets you view and organize maps, way-points, routes and tracks. Create Garmin Adventures to share with friends, family or fellow explorers. BaseCamp displays topographic map data in 2-D or 3-D form on your computer screen, including contour lines and elevation profiles. It also can transfer an unlimited amount of satellite images to your device when paired with a Birds Eye Satellite Imagery subscription.
