OpenSeaMap is a worldwide open source project for creation of a free nautical chart.
History and fundamentals
OpenSeaMap was created in 2009 in response to a great need for freely-accessible seafaring maps. OpenSeaMap's goal is to add nautical and tourism information that would interest sailors OSM, and to present it in a pleasing way. This includes beacons, buoys and other seamarks, port information, repair shops, ship supplies and much more, but also shops, restaurants and places of interest. OpenSeaMap is part of OpenStreetMap and uses its database.
OpenSeaMap is an open Sea Map, and also open for future developments. The basemap is rendered using the OpenStreetMap-data. This map is extended with nautical data that is saved in the OSM-Database as well. OpenLayers is used to overlay additional nautical Information, which can be displayed in a popup by clicking on the map.
OpenSeaMap can be viewed online.
In the future, you will be able to download the current map onto your laptop for your cruise.
We are still searching for a way to display water depth and a method of displaying the profile of the sea bed. We are also experimenting with AIS. Of course we will provide a list of ports and later also a port guide.
The data scheme applies to the international norm IHO-S-57, as published by the IHO. This allows a simple exchange of data with other ECDIS-Applications. Because of the complexity of attributing seamarks, there will be (unlike the usual OSM procedure) a strict separation between database as backend and the frontend, to allow users to input data without knowing S-57. A graphical user interface will be provided in the form of three editors.
