Marine data sets
At the UKHO, our teams collate, process and publish terabytes of data – from bathymetric profiles depicting the seafloor, to astronomical data on the celestial objects above us. Through our ADMIRALTY Marine Data Portal, users can not only access extensive data on bathymetry, but also information on maritime limits, ships' routeing, wrecks and obstructions, and offshore infrastructure.
As well as supporting the evolving needs of mariners and existing users of our ADMIRALTY products and services, these data sets can also support decision making in new markets across the blue economy.
