Great Britain 1:250K Database Digital Elevation Model: Bartholomews
Listed in NASA Earthdata CMR
Description
The following text was abstracted from Bruce Gittings' Digital Elevation Data Catalogue: 'geo.ed.ac.uk/home/ded.html'. The catalogue is a comprehensive source of information on digital elevation data and should be retrieved in its entirety for additional information. The Great Britain 1:250K Database (doesn't include Northern Ireland thus not the "UK" database - NI is part of the Ireland (now European database)) costs #2850 or #65 per 100km National Grid tile.
Horizontal accuracy +/-200m. Vertical accuracy is approx. +/-10m - but depends on how you take account of horizontal displacements. The size is 70mb in Arc/Info format.

Discounts are normally available for educational establishments. For research and teaching (excluding commercial research) the data can be obtained at very low prices through CHEST at Manchester University Computing Centre (Tel: 061 275 6099). Higher education users in ALL European countries excluding the former Warsaw Pact area (for the time being) may obtain data through CHEST following a new deal.
