Itineraries provide the ability to record information about a specific trip, together with useful waypoints and routes. You may also wish to show and share previous track logs that relate to the trip or add track logs after the trip for future reference.
Additionally you can create and modify routes and waypoints. You can also modify track logs.
Although routes and tracks are quite similar in that they both can denote a path, they are treated a little differently by the system.
Itineraries are listed in descending start date order. Itineraries with no dates are listed in alphabetical order prior to those with dates.
You can only edit itineraries that you created yourself. You cannot edit itineraries shared with you by others.
