One Answer:
You can download all GPS points from http://planet.openstreetmap.org/gps/ and then you can compute the speed and direction by analysing the locations and timestamps of successive points in a track. These values are not explicitly given, you have to write code to compute them. answered 10 May '13, 16:03  Frederik Ramm ♦ |
Latitude, longitude, speed and direction of what, exactly? Vehicles? Pedestrians, cats, flying pink unicorns?
Or elephants.
