G4ng is a service that is mainly geared towards people who like traveling. It will basically let them save all their spatial data in a unified place, and then not only access it whenever they want but also share it with other fellow travelers.
This data includes tracks, routes and waypoints and it can be visualized both in Google Maps and in you own customized maps. When you are viewing it you will be able to edit every single waypoint, join tracks and also geotag pictures and text entries.
Whenever you are setting down a route you will be capable of individualizing it using polylines. And you will also be allowed to suggest alternate routes just in case something has gone wrong and the one who is reading the map at a later date needs to make his way to the original destination (for example, a hostel) before night comes.
When it comes to sharing such data, now, it is vital to stress that you can manage its degree of visibility. If for any reason or the other you don’t want any waypoint or route to be shared then you can proceed to keep it entirely private, or shareable only with a selected group of individuals (including your family, of course).
