ADMIRALTY Marine Data Portal

As a Public Authority, the UKHO makes relevant data sets available in compliance with the ‘Infrastructure for Spatial Information in Europe’ (INSPIRE) initiative.

The ADMIRALTY Marine Data Portal provides access to marine data sets held by the UK Hydrographic Office within the UK Exclusive Economic Zone (EEZ). The ADMIRALTY Marine Data Portal replaces the INSPIRE Portal as the place to search and download data sets regarding Maritime Limits and Boundaries, Ships’ Routeing Measures and Bathymetry.

As a Public Authority, the UK Hydrographic Office makes relevant data sets available under the Open Government Licence in compliance with the ‘Infrastructure for Spatial Information in Europe (INSPIRE) initiative. The following data sets have been added to the ADMIRALTY Marine Data Portal:

  • Maritime limits and boundaries around the UK as maintained by the UKHO’s ‘Law of the Sea’ department.
  • Ships’ Routeing Measures as approved by the International Maritime Organisation (IMO), and/or the Maritime and Coastguard Agency (MCA) (as National Competent Authority).
  • Bathymetric surveys from various sources including over 4,000 bathymetry surfaces from 1970 to present day.

The bathymetry data is updated every three months and a large number have been funded by the MCA, an executive agency sponsored by the Department for Transport, under the Civil Hydrography Programme.

We have been accredited by the Marine Environmental Data and Information Network (MEDIN) as the National Data Archive Centre for bathymetric surveys. Therefore, we have included access to relevant bathymetric surveys held in our Data Archive Centre as part of our ADMIRALTY Marine Data Portal.
