Ordnance Survey (OS) has launched the latest expansion of the national map of Great Britain (GB), the OS National Geographic Database (OS NGD).

Since its initial launch three-and-a-half years ago, the database has expanded into a collection of datasets to deliver the most detailed and data-rich digital map in history, bringing together a high volume of authoritative geographic data for GB into one location.

This is the biggest change to OS data access in a generation.

OS has now released 16 data collections and 70 major data enhancements into the OS NGD to make it the richest map of Britain ever created.

The update includes full coverage of bus and cycle lanes, supporting local authorities and central government in promoting Active Travel and public safety. It also adds improved postcode unit areas and points data, a new retail areas dataset which provides a geographical view of retail activity across GB.

OS's structures data has also been enhanced with third party-bridge information which helps identify the location of emergency incidents.

2026 is the 225th anniversary of the creation of OS's first map, which was commission with the purpose of protecting national security.

Tina Kennedy, Chief Customer Officer at OS, said: “Providing detailed, trusted and accurate data has been part of Ordnance Survey’s DNA since its first map was created 225 years ago. OS has since evolved into a data powerhouse which supports many different sectors with critical and actionable insights - from insurance and property to local authorities under pressure to meet biodiversity net gain targets. And despite the unprecedented scale of datasets already delivered with the latest data release, OS continues to deliver further enhancements and products to meet the growing needs of our customers and deliver greater value, because high-quality data is an asset for everyone.”
