SeaMap shows nautical information on a map. This is useful when you go out sailing with your boat. It includes beacons, buoys, SIGNI, IALA-A and other navigation aids. The information is obtained from OpenSeaMap which is part of the OpenStreetMap project. It mainly covers parts in Europe, like the Baltic Sea and the North Sea. But more regions are covered like for example areas in Australia.
