OS Terrain 50 is a digital elevation dataset for Great Britain – actively maintained by the Ordnance Survey: Two versions of the dataset exist: one vector-dataset that provides height contours with a 10 m vertical spacing and one gridded dataset with a grid-spacing of 50 m. The resolution of the dataset corresponds to a 1:50000 mapping scale. Update frequency is once a year – in July. Two versions are acessable from with windPRO - the 2018 version and the version from 2014.

Coverage

Coverage is for the whole of Great Britain (but not including Northern Ireland).

Usage Notes

  • For projects in Northern Ireland, we recommend the OSNI Open-Data 10m gridded digital elevation dataset.
  • For projects in Wales - also consider the LiDAR dataset available in the Wales Elevation Model.
  • Need higher resolution data? OS maintains a commercial, higher resolution dataset 'OS Terrain 5'
  • The user guide and technical specification for the OS Terrain 50 dataset is available here in this pdf-file.
  • We recommend using the most recent version of the data (e.g. for windPRO: the 2018 release)
