Ships in the Water
Project Name: Live Ships Map
Details: This map collects recent data about many large passenger, cargo, and pleasure boats in the waters around the world. All large ships traveling in open water are required to have a transponder that relays the ship's name, position, speed, and course, as well as other statistical information about the vessel. The information on this map is part of an open-source project run by the University of the Aegean in Greece. Check out this FAQ to learn more.
