Norwich Union, Direct Line and Churchill are testing an aerial photography device that could slash the cost of motor claims investigations by up to 80%.

The web-based Supra National Aerial Photography (SNAP) gives in-depth area information to an accuracy of 12.5 cm across the majority of the UK.

Claims handlers can view property and road locations as part of their investigations, to generate a locus report, or to establish liability in a motor incident.

The system was developed by InFront Solutions and Infoterra of BAE Systems.

Martin Wiggins, InFront Solution's sales and marketing manager, said: "Now, it costs up to £100 for a claims investigator to make one visit. With SNAP, each photograph will cost up to £20 plus VAT. It could reduce claims inspection costs by 80%."
