Ordnance Survey updates aerial photography layer

Ordnance Survey announces a significant update to its flagship aerial photography product, OS MasterMap Imagery Layer, ensuring that it remains a market leading proposition for aerial imagery in Great Britain.

More than 120,000 km.sq of new and updated aerial photography, the equivalent to half of Britain, has been made available to customers over the last 12 months. This is the result of an intense period of imagery production and follows successful flying seasons over the last two years.

David Henderson, Senior Product Manager at Ordnance Survey, says, “With the introduction of our digital mapping camera and a more integrated approach to data capture and processing, we have made a dramatic improvement to the currency of our imagery during the last 12 months. Furthermore, by integrating our programmes of image and topography data collection we can offer ever greater synchronicity between our products.”

OS MasterMap Imagery Layer offers seamless coverage of Great Britain. The high resolution imagery is colour balanced and fully orthorectified, meaning that it accurately reflects the position of features at ground level without distortion. This also ensures alignment with all the other layers in the OS MasterMap family.
