Ordnance Survey has announced it will supply high-quality digital aerial photography via a three-year licence to Avon and Somerset, which enables seamless colour data from the OS MasterMap Imagery Layer to be used for visualisation and analysis across the Force`s area.
The orthorectified imagery is specifically 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,” said Ordnance Survey`s Director of Sales and Market Development, James Brayshaw. “This means the imagery truly and accurately reflects the position of every feature at ground level without distortion. We are delighted that Avon and Somerset have chosen our proposition to meet their needs for accurate information to support their services.”
Data in the Imagery Layer is captured by Ordnance Survey`s flying unit and commercial partners, with only the best available 25-cm resolution and 24-bit colour output selected for use. This is to ensure that customers have access to nationally consistent and accurate coverage.
“The unique benefit for us is that the data is orthorectified to the map,” said Kevin Neenan, Avon and SomersetÂ’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.”
As well as ensuring its imagery is orthorectified and complementary to other OS MasterMap layers, Ordnance Survey also attaches metadata to each image so users such as Avon and Somerset can trace and track information for the clearest possible understanding of the area.
