Real-Time Ship Tracking on Google Maps

The International Maritime Organization (IMO) requires all vessels over 299GT to carry an AIS transponder on board. The transponder transmits data on position, speed and course, among some other static information, such as the vessel’s name, dimensions and voyage details. Thanks to this AIS data there are now a lot of Google Maps mashups showing the real-time positions of ships around the world.
Being an old retired vessel follower and early implementer, I am always interested in possible improvements that can be made using today's technology. Appears all we need is a few volunteers with AIS receivers to cover inland waterways of the US! --- Monte HinesHere are a few ship tracking maps ...
