OpenSeaMap is a starting OpenStreetMap subproject to create some free nautical map with contributions both from official public data (with no copyright) and passionated individuals.

As the backend structure for the data is based on the s-57 vector format (used by official ENC), it could be a good tool to :
  • develop some cartographic online interface for implementing the info from the official Notices to Mariners (NTMs) which provides timely marine safety information for the correction of all the official navigation paper charts
  • use the power of collaborative crowdsourcing for implementing nautical POI such as port information, marinas, repair shops, shipchandlers, marine electronic dealers...
Of course, this interesting initiative can't be a 'competitor' of the official Hydrographic Services which are using sophisticated technical means (multibeam, RTK GPS, Lidar...) in order to propose nautical charts more increasingly accurate.

In this way, as the final result is open to all, why not imaging some OpenSeaMap layer in the Marine GeoGarage to get official chart corrections from NTMs and a complementary marine local guide ?
