Key facts
Contents & fields
The dataset is a tiled raster dataset in GeoTiff format, each tile 5km×5km aligned to the Ordnance Survey National Grid, spatial resolution 2m, elevations in metres referenced to Newlyn (St Marys for Isles of Scilly). Data also available as ESRI Image Service. Metadata index catalogue layer provides information on elevation data source (LIDAR or bathymetry), surface type, coastal monitoring region, geoidal model and transformation models. Catalogues downloadable in shapefile, ESRI File Geodatabase and GeoJSON.
- Elevation——Elevation value in metres
- Surface type——DTM or DSM
- Source——LIDAR or Bathymetry
- Coastal monitoring region——Coastal monitoring region
- Geoidal model——Geoidal model
- Transformation model——Transformation model
