Using our aerial imagery to check road markings, tree canopies or site entrances cuts down the need for site visits, so you can save money and manage time more efficiently.
For engineers, for surveyors, for planners, Imagery Layer is a revelation. It's aligned to OS MasterMap Topography Layer and is incredibly detailed, expertly colour-balanced and corrected for geometric distortions.
OS MasterMap Imagery Layer is an off-the-shelf product for the whole of Great Britain. You can get it under perpetual use terms – ideal for projects – as well as fixed-term licences.
Active capture programme
More than 97% of our imagery is less than five years old; 90% is less than three years old. Check imagery currency on our interactive map.
Up-to-date imagery and data
OS MasterMap Imagery Layer uses the same source imagery that underpins our large-scale data updates. Our processing software produces true-orthorectified imagery, removing building lean from aerial imagery to give you a consistent top-down view.
You can easily interpret the detail
You can easily spot properties with solar panels, conservatories and other home improvements, thanks to the layer's 25cm resolution. This makes the product ideal for planning and environmental monitoring.
