Alternative title(s)

Abstract

This dataset contains Digital Elevation Model (DEM) filed download south files for the waters surrounding the United Kingdom to a depth of 200 metres. This resolution is 1 arc second covering primarily the coastal areas. Geographic coordinates were used throughout and the DEM is referenced to the ETRS89 datum horizontally and Chart Datum vertically. All input data was made available under licence by the UK Hydrographic Office (UKHO) to Defra for the purpose of DEM creation. Attribution statement:

Lineage

ETRS89 approximates to the WGS84 datum and as far as the input data is concerned, the two datum’s have been used synonymously, unless otherwise realised. Chart Datum approximates to the level of Lowest Astronomical Tide (LAT) and was used as this is the standard vertical reference datum of the source data received from the UKHO.
