New PSGA data will help speed up emergency response times

New Public Sector Geospatial Agreement location datasets released by Ordnance Survey will help deliver improved public services.

A new selection of location datasets, including two new products, were recently (Thursday 28 March) released as part of the Public Sector Geospatial Agreement (PSGA). The new data and products have been delivered by Ordnance Survey (OS) and are set to support customers across a range of markets, including the emergency services, sustainability, land management, transport and property both in public and private sectors. 

One of the new products is the OS Emergency Services Gazetteer (ESG), which will enhance the way that emergency services respond to and manage incidents. The OS ESG is a comprehensive and maintained database of locations. It will contain 1.3 million features (names, places and objects), such as motorway, road junctions and roundabouts. 

The OS ESG was developed in close collaboration with the blue light community and will continue to grow over time as new features are added. It is designed to equip responders with the precise location information they need to act quickly to save lives and property during emergencies. It is particularly effective in identifying the location of areas that have no addresses, like named cliffs and named waterfalls. It will provide a single, unified source of truth for accurate location information, aiding both those in control rooms and on the front line. 

The other new product is the OS Multi-modal Routing Network that has been developed in response to customer feedback and brings all OS transport information together in one place, reducing the effort required in preparing the data for use in routing applications. Local authorities will be able to use this data to plan safe routes to school and colleges, and emergency services will be able to improve their emergency planning for incidents at specific locations. 

The release also includes enhancements to the OS National Geographic Database (NGD) such as: 

  • buildings data – which will help users develop a better understanding about the energy performance of buildings 
  • new Field Boundary and land cover information - beneficial for a range of environmental sector customers, environment agencies across England, Scotland and Wales, major landowners and farmers, as well as both local and central government in delivering net zero ambitions 
  • enhancements like the Tram Track attribution – showing where trams are present on the road network, beneficial for road safety and streetworks 

For more information on the release, please visit the OS Data Hub. 


The PSGA is a 10 year contract between the government and Ordnance Survey (OS), managed by the Geospatial Commission, for the provision of geospatial data across multiple themes, including buildings, transport, structures, addressing and land. The contract delivers key data to public sector members for use in everyday settings to support provision of critical services to the public. 

The PSGA provides access to new and existing data via the OS Data Hub, including delivery of data via API and downloads. Over its term the PSGA will deliver approximately 70 new data sets and ensure the public sector has access to core foundational geospatial data that is needed to deliver effective and efficient public services.
