The Civil Hydrography Programme

Systematic surveying of the UK’s coastal waters is administered by the Maritime & Coastguard Agency (MCA) under the Civil Hydrography Programme, with technical oversight, data validation and onward charting undertaken by the UK Hydrographic Office. Under the programme, the MCA has issued a number of long-term commercial contracts to ensure accurate hydrographic information is gathered for updating the nation’s nautical charts and publications.

View the MCA Civil Hydrography Programme website.

Routine resurveys are undertaken in areas where the seabed is highly mobile. We analyse these surveys to identify changes that have occurred and apply updates to charts if necessary. We also assess whether the limits and survey frequency should be revised.

ADMIRALTY surveys of the UK (Q6090)

The ‘limited use’ chart Q6090 shows the limits and standards of ADMIRALTY surveys, including contract surveys to ADMIRALTY specifications around the United Kingdom. Not all of these surveys are available in digital format. For more detail on the availability of surveys, see our ADMIRALTY Marine Data Portal guide.
