Acquiring hydrographic data
The Hydrographic Service has up-to-date data sets at its disposal containing information that is processed into products. The Service offers these hydrographic data in various ways.
Requesting re-use of nautical charts or hydrographic publications
Nautical charts and hydrographic publications are protected by copyright. A licence must therefore be obtained for the re-use of these publications. In some cases, the licence is free of charge. You can apply for a licence using the form below.
The United Kingdom Hydrographic Office (UKHO) processes licences subject to a fee on behalf of the Hydrographic Service. You can also apply to the UKHO for licences for several other countries.
Re-use of hydrographic data is possible via web services and portals. The Hydrographic Service offers these data for instance at the Open Data Viewer as a partner of the Marine Information and data Centre. Further information about web services and portals is contained in the memo Online availability of data from the Hydrographic Service.
