OS MasterMap Imagery Layer
The OS MasterMap Imagery Layer® comprises the best available aerial images, edge-matched and orthorectified to align with other OS MasterMap layers.
Product DetailsThe 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
- 3D visualisation

The OS MasterMap Networks - Water Layer® is a detailed, accurate and up-to-date vector dataset of Great Britain’s water network - rivers, streams, lakes and canals.
Product detailsThe OS MasterMap Networks - Water Layer® is the only detailed, heighted water network of Great Britain showing the flow and precise course of rivers, streams, lakes and canals.
It offers the most accurate view of all watercourses across the whole of Great Britain created, in collaboration with the Environment Agency and Scottish Environmental Protection Agency, to a consistent specification and update schedule – so it can help support flood risk management decisions and the sharing of information between national and local organisations.
Accurate physical properties of watercourses enable modelling in 2D and 3D like never before, thanks to the clear and detailed information about river flow, gradient and river widths, along with its precisely mapped course.
The data maps a wide range of features, from aqueducts to tunnels with full flow direction and for the first time the network of underground watercourses – inferred from the entry and exit points.
OS MasterMap Networks - Water layer® is ideal for:
Planners, for surveyors, for engineers – this Layer offers the potential to model in 2D and 3D like never before, thanks to the clarity of river flow, gradient and river widths.
