The Digital Terrain Model (DTM) is a bare earth model, posted at 5m with a vertical accuracy of less than 60cm RMSE (root mean square error). The model represents the bare...

Elevation contour lines within the Wye catchment at 10 and 20 metre intervals. The contour lines have been digitised from a scanned topographic map.

This high resolution (1m) spatial dataset provides elevation and terrain information for England and Wales. It includes a digital terrain model (DTM) and a digital surface model...

Hydrologically corrected digital terrain model (DTM) of Plynlimon catchments. The DTM was derived from digitised elevation data from scanned topographic maps.

Elevation contour lines within the Severn catchment at 10 metre intervals. Digitised from the scanned topographic maps.

Spot heights (elevation values in metres) for areas within the Plynlimon catchments; digitised from scanned topographic maps of Plynlimon Catchment Areas.

Coastal Topographic Surveys are height transects that form part of the Anglian Coastal Monitoring Programme. A surveyor using a GNSS (Global Navigation Satellite System) staff...
