Articles for Ordnance Survey

Ordnance Survey (OS) is not merely a map-maker; it is the custodian of Great Britain’s geographic identity. As the national mapping agency of the United Kingdom, OS maintains the most detailed and frequently updated database of a nation’s landscape anywhere in the world. From its military origins in 1791 to its current status as a state-of-the-art geospatial data powerhouse, Ordnance Survey Limited provides the "trusted location data" that underpins the very fabric of British society. Headquartered in Southampton, Hampshire, OS is a public corporation that manages the National Geographic Database (NGD)—a colossal digital repository containing over 600 million individual features. Whether it is supporting emergency services in life-critical situations, enabling the rollout of 5G infrastructure, or helping millions of hikers navigate the Scottish Highlands via the OS Maps app, the influence of Ordnance Survey is ubiquitous. 230 Years of Innovation: A Historical Perspective The story of Ordnance Survey began on 21 June 1791, fueled by the threat of Napoleonic invasion. Under the leadership of Major-General William Roy, the agency was tasked with the systematic mapping of the southern coast of England to assist military defense. The name "Ordnance" itself reflects its origins within the Board of Ordnance, the government body responsible for the nation's weaponry and engineering. Over two centuries, OS transitioned from hand-drawn copperplate engravings to satellite-derived vector data. Today, under the leadership of CEO Nick Bolton, the organization employs over 1,200 professionals, including cartographers, data scientists, and remote sensing experts, ensuring that Great Britain remains one of the most precisely mapped nations on Earth. The Power of the OS National Geographic Database (NGD) At the heart of the business lies the OS National Geographic Database. This is the single source of truth for the British landscape. The NGD is updated up to 20,000 times every single day using a combination of: Aerial Imagery: A dedicated flying unit captures high-resolution photography. Ground Surveys: Over 230 surveyors use highly accurate GPS (GNSS) equipment to verify changes on the ground. Satellite Data: Modern remote sensing techniques provide rapid updates on land usage. This database doesn't just show roads and rivers; it identifies every building, fence, path, and even individual addresses (via AddressBase) with centimeter-level precision. This level of detail is essential for the Public Sector Geospatial Agreement (PSGA), which grants government agencies access to OS data to improve public services. Core Products and Services 1.
