Case Study: London Ambulance Service achieves faster responses and improved coverage with Ordnance Survey mapping

London Ambulance Service - Customer Case Study

The London Ambulance Service (LAS) handles about 5,400 emergency calls a day with more than 250 vehicles on duty, and needed a better way to maintain an overview of vehicle locations, direct crews to standby points and predict incident hotspots. Using Ordnance Survey mapping data accessed via the Public Sector Mapping Agreement, LAS developed Geotracker, a real-time web-based mapping solution to meet those challenges.

Ordnance Survey’s datasets (including OS MasterMap ITN and Topography layers) power Geotracker’s routing engine, which uses historic road speeds and the ITN layer to continually calculate where ambulances can reach within eight minutes, predict hotspots, detect coverage gaps and let operators drag-and-drop units to test redeployment. The result is a fault‑tolerant, network‑wide real‑time coverage display that improves dispatch decisions and resource planning, with measurable outputs such as calculated eight‑minute reach and demonstrable increases in predicted coverage when vehicles are redeployed.
