OS Terrain® 50 is a height product for Great Britain available to all, for free, to download and use through OS OpenData™. Sharing a common data source with OS Terrain 5, OS Terrain 50 offers a simplified digital terrain model adding the third dimension to the visualisation and analysis of large landscape areas.

Typical applications for this product include a range of professional applications such as drainage analysis, radio wave propagation, asset management and environmental assessment and also in consumer applications providing landscape visualisations for outdoor exploration and navigation applications.
OS Terrain products are published in a range of common data formats, maximising the ease with which these products can be used together. OS Terrain 50 benefits from comparatively lower data volumes increasing its ease of use and reducing data storage volumes whilst at the same time still enabling a realistic view of the landscape.
OS Terrain 50 is a significant development for users of OS OpenData, as for the first time an updated and maintained height data product is available. Sharing source data with our large scale products means that we can offer currency to which users of open data products have not previously had access.
