3d tracking is a revolutionary way to use the Internet to either monitor the movements of a live vehicle/person or to display a previous route that's been travelled.
The vehicle/person's path is displayed as a line on either Google Earth or Google Maps with details of the speed at each point along the route.
This allows you to follow the progress of a live vehicle, watching the points appear on the map as the vehicle moves. Alternatively you can view the previously recorded path that a vehicle or person moved along.
