The aerial images give added context to features which exist within other (vector) OS MasterMap layers and allow interpretation of other features not identified within the vector datasets. The data is rigorously checked for quality to maintain a consistent standard of both positional accuracy and image quality.

Additionally Ordnance Survey processing software produces true-orthorectified imagery, removing building lean from aerial imagery to give you a consistent top-down view.

Aerial imagery is ideal for checking road markings, tree canopies or site entrances, cutting down the need for site visits, so you can save money and manage time more efficiently.​

Purchasable as both a traditional raster cut-out of a user defined area or as web services.

OS MasterMap Imagery layer is ideal for:

• Planning
• Site location and evaluation
• Land use classification and analysis
• Transport and infrastructure
• Asset management
• Environmental analysis
• Flood mapping
