About the ADMIRALTY Marine Data Portal

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, ships바카라 사이트� routeing measures, bathymetry and more.

As a Public Authority, the UK Hydrographic Office makes relevant data sets available under the Open 바카라 사이트 Licence in compliance with the 바카라 사이트業nfrastructure for Spatial Information in Europe (INSPIRE) initiative.

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.
