With the use of AIS, Hi Def San Francisco has developed an Google Map Ship Tracker, which will track the real time location of ships, speed of the ships, types of ship and so on. In every 15 seconds the Hi-Def will updates the ships location in Maps. When you click on any images the most recent images will be visible on your screen on the maps. Commercial vessel, large pleasure craft will be updated on maps. Checkout the Quick Time Video of the day’s traffic which was tracked on Google Map.
