Visualize and share your GPS
Many route planner applications and GPS devices track routes into GPX files. GPX stands for GPS eXchange. (Read more about the GPX format at Wikipedia.)
If you take a walk or any other kind of route outside with your GPS device and want to share your route afterwards, RouteView is a handy tool.
Load a .gpx file and share it with others. When you share a route, a snap shot of the route map will be sent along with the data, via email or iMessage.
