The product is designed to complement the use of Ordnance Survey’s large-scale products and is maintained through an integrated capture programme ensuring an unrivalled level of data currency across our large scale products. OS MasterMap Imagery Layer is updated on a continuous revision cycle and offers the most current view of Great Britain, over 97% of the imagery is less than 5 years old.

OS MasterMap Imagery layer is a key data product in many of Ordnance Survey’s markets, in both the public and private sectors. Used extensively for risk management, site planning, property development, asset management, agricultural services and environmental monitoring.

It can be combined with a wide range of other sources of geographical data and supporting your analysis and decision making.
