1:50 000 Scale Colour Raster

The digital alternative to our popular OS Landranger paper map series, this is a high-quality map of Great Britain, available in 20km square tiles.

1:50 000 Scale Colour Raster is a must-have map in any navigation app or device for walkers and cyclists. It depicts the landscape with superb detail and clarity.

For local planners, this map helps you spot brownfield sites ripe for development, and analyse the quality of local transport links. Railways and important roads are clearly colour-coded.

1:50 000 Scale Colour Raster helps emergency control centre staff respond more effectively to calls. Using clearly shown landmarks, they can ask distressed callers if they can see the local pub or church, to pinpoint incident locations quickly.
