OS Terrain data has been created from a source that is also used to update other OS large-scale data products and is designed to be interoperable with other OS digital datasets such as MasterMap Topography Layer and VectorMap Local.
OS Terrain 5 is a mid-scale height dataset that includes detailed modelling of significant landscape and infrastructure features such as road, rail, quarries and lakes. OS Terrain® 5 is available as a set of contours with a 5m vertical interval, along with spot heights and mean high and low water marks. It is also available as a Digital Terrain Model (DTM) consisting of height values at each intersection of a 5m grid.
OS Terrain® 50 is a small-scale height dataset that is ideally suited to landscape visualisation and analysis over large areas. OS Terrain® 50 is available as a set of contours with a 10m vertical interval, along with spot heights and mean high and low water marks. It is also available as a Digital Terrain Model (DTM) consisting of height values at each intersection of a 50m grid.
