UK-OS Terrain 50
Introduction
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. The version delivered with windPRO is from 2014.
Coverage
Coverage is for the whole of Great Britain (not including Northern Ireland). For projects in Northern Ireland, we recommend the OSNI dataset [LINK]. For projects in Wales - also consider the LiDAR dataset [Link].
