OS MasterMap Imagery Layer

OS MasterMap® Imagery Layer yields compelling information that you cannot get from mapping alone, such as road markings, habitats, land use, vegetation, pipes and cables, utilities infrastructure, roof types, and building access.

Coverage

  • Large scale - local

Data use

  • Height and imagery

Data format

  • Raster

Expertly colour-balanced and corrected for geometric distortions (orthorectified), OS MasterMap Imagery Layer is seamless aerial photography of the highest quality that is available off-the-shelf at a consistent 25 cm resolution for the whole of Great Britain.

Flying high in 2014

We have already flown 30,000 kms of imagery since the flying season opened in Spring. This imagery is being orthorectified and quality assured to high standards, and will be refreshing the Imagery Layer soon. Check the currency for your area with our new interactive currency map.

True-orthorectified imagery

Following significant investment in our cameras, processing and supply systems, OS MasterMap Imagery is better than ever before. Our new cameras and processing software are producing true-orthorectified imagery which removes building lean from aerial imagery to provide a consistent top-down view. This consistency makes the imagery appear even more like OS MasterMap Topography Layer to aid interpretation and improve geometric synchronicity.

Flexible licensing

We’ve added a perpetual use licence to our licensing options to allow you to purchase OS MasterMap Imagery Layer for standard business use in perpetuity. This enables a one-off purchase, which is perfect for project work that does not require data updates and annual licensing.

We refresh it continuously to provide you with the most up-to-date view possible – see the currency of coverage for your area on our new interactive map.

Synchronised with our large scale data

Our source aerial photography is used to update our core databases so you can be sure that features on the ground appear consistently in our various large-scale datasets, notably OS MasterMap Topography Layer and OS Terrain 5.

Our customers use it extensively for risk management, site planning, property development, asset management, agricultural services and environmental monitoring. Together with our other large-scale products and your data, OS MasterMap Imagery Layer enables powerful analysis.

How to use our data

We provide the most accurate and up-to-date geographic data in Great Britain.

Our data will need to be integrated in a Geographic Information System (GIS) to allow you to view, edit, overlay and manage different data formats and sources.

Our products, depending on their formats, will require different software. Some also require translation tools so please check with the system providers for the products you are interested in.
