Core offering

The UK Hydrographic Office collects, processes and shares marine geospatial data from seabed to surface and converts it into the Admiralty portfolio of navigational products and services, including digital vector and raster charts, digital nautical publications, paper charts, tide tables, and tidal and astronomical data. The organisation serves as Primary Charting Authority for 63 coastal states and supports SOLAS-compliant navigation, with over 90% of large internationally trading ships carrying Admiralty products on board.

Product overview

The United Kingdom Hydrographic Office (UKHO) operates the Admiralty portfolio of maritime navigation products and services—the world's most comprehensive range of marine geospatial information. The portfolio follows a platform-plus-services architecture centred on the Admiralty Vector Chart Service (AVCS) and Admiralty Raster Chart Service (ARCS) as the core digital chart services, supplemented by Admiralty Digital Publications (ADP) including the Admiralty Digital List of Lights, Admiralty Digital Radio Signals, Admiralty TotalTide, Admiralty e-Nautical Publications, Admiralty Digital Sailing Directions, and NavPac. Supporting paper chart products include Standard Nautical Charts and the Admiralty Small Craft Chart Service, alongside traditional nautical publications (Admiralty Sailing Directions, Admiralty List of Lights and Fog Signals, Admiralty List of Radio Signals, Admiralty Tide Tables, Admiralty Mariner's Handbook, Ocean Passages for the World). The Admiralty Digital Catalogue and Admiralty S-100 Data Catalogue provide cataloguing and discovery services. Safety-critical services include Notices to Mariners, Radio Navigational Warnings, Hydrographic Notes, and the S-100 Service for next-generation IHO S-100 standards including S-102 Bathymetric Surface. The ADMIRALTY Marine Data Portal provides data access alongside dedicated services for seabed mapping, tidal data, astronomical data, and the 2022-launched UK Centre for Seabed Mapping initiative. UKHO supports defence operations through Additional Military Layers and specialist ENC products for the Royal Navy's Carrier Strike Group.

Direct peers

• Service Hydrographique et Océanographique de la Marine (SHOM): SHOM is France's national hydrographic office under the French Navy, performing primary charting for French overseas territories. It is directly comparable to UKHO in terms of defence-linked governance structure, Primary Charting Authority role, ENC production, and international shipping compliance mandate.
• National Oceanic and Atmospheric Administration (NOAA) Office of Coast Survey: NOAA's Office of Coast Survey is the US hydrographic authority producing nautical charts for American waters. It is the closest functional peer to UKHO, sharing the same regulatory mandate under SOLAS, primary charting authority status for US coastal states, and overlap in ENC and raster chart products serving international shipping.
• Australian Hydrographic Office: Operated under the Royal Australian Navy, the Australian Hydrographic Office is a defence-affiliated primary charting authority producing digital and paper charts for Australian waters. Comparable to UKHO in scope, governance model, and SOLAS-mandated product portfolio.
• Norwegian Mapping Authority - Hydrographic Service: Norway's hydrographic service operates as the Primary Charting Authority for Norway, producing ENCs and nautical publications comparable to UKHO's Admiralty range. Both serve major international shipping markets and share S-100 standards development through IHO membership.

Emerging players

• IIC Technologies: IIC Technologies provides hydrographic survey, digital chart production, and marine data services for national hydrographic offices and commercial clients globally. It is a partial competitor in chart production and a partner for many Primary Charting Authorities, including overlap with UKHO's data services.
• Fugro: Fugro is a major private hydrographic, geotechnical, and seabed survey company providing high-resolution bathymetric data services. While not a chart authority, Fugro is an increasingly important upstream data supplier and potential partner/competitor to UKHO in seabed mapping and marine geospatial data markets.
• ChartWorld GmbH: ChartWorld operates an ECDIS chart management and route planning platform and is listed as an ECDIS integration partner for AVCS. It is an adjacent commercial player in digital chart services that overlaps with UKHO's downstream distribution to the maritime shipping market.

Others

• Teledyne CARIS: Teledyne CARIS provides hydrographic data processing software and workflow tools used by hydrographic offices and surveyors worldwide, including by UKHO. It is an enabling technology supplier to the hydrographic chart production ecosystem rather than a direct chart competitor.

Broad incumbents

• Jeppesen (Boeing): Jeppesen, a Boeing subsidiary, provides commercial maritime and aviation charts and digital navigation solutions. It operates as a broader incumbent in the navigation data space, competing with Admiralty products in commercial shipping ECDIS subscriptions while serving adjacent aviation markets.
• National Geospatial-Intelligence Agency (NGA) Maritime Safety Office: NGA's Maritime Safety Office produces and distributes official US government charts, publications, and navigational warnings globally. It operates at a similar scale to UKHO within the US defence and intelligence ecosystem and serves as a counterpart for international shipping SOLAS compliance.
