While watching a position, the direction of travel in degrees relative to due north and speed in meters per second if available, else 0 of not available.
What is a "due North" ? Do you mean a "true" north ?
And since I am on the subject of Geolocation, can I assume that if I use "Request Location" instead of "Watch Location", after the first "On location update" triggers, the GPS chip will be released right ?
Or do I have to still call "Stop watching" just in case resource wise ?
