Avon and Somerset police to get high-quality digital aerial photographs from Ordnance Survey


UK, 10 July 2006: Ordnance Survey announced on July 10 the supply agreement for its high-quality digital aerial photography. A three-year licence for Avon and Somerset Police enables seamless, colour data from the OS MasterMap Imagery Layer to be used for visualisation and analysis across the force’s area.

“The unique benefit for us is that the data is orthorectified to the map,” says Kevin Neenan, Avon and Somerset Police’s Reprographics Manager. “By overlaying the imagery with building outlines, road names and other information from OS MasterMap across an identical area we have a much greater depth of information than the mapping alone. We can pinpoint the detail of surrounding terrain much more quickly, which is ideal for making decisions about the planning of operations and incident response.”

The orthorectified imagery is designed to complement other geographic information in the OS MasterMap Topography, Address and Integrated Transport Network Layers, providing a valuable spatial framework for operational planning and logistics.

“Each pixel in the image is positioned as accurately as possible to the underlying coordinate system on which OS MasterMap is produced,” says Ordnance Survey’s Director of Sales and Market Development, James Brayshaw. Ordnance Survey also attaches metadata to each image so users such as Avon and Somerset Police can trace and track information for the clearest possible understanding of the area. Ordnance Survey is releasing the Imagery Layer in a national roll-out as data becomes available.
