    "description": "Marine Themes Digital Elevation Model (DEM) of the Seabed generated from single beam echo sounder (SBES) and multi beam echo sounder (MBES), where available, and Electronic Navigational Chart (ENC) or GEBCO derived data where not. The 1 arc second resolution data set is divided and supplied as 0.5 degree x 0.5 degree tiles. The 6 arc second resolution data set is divided and supplied as 2.0 degree x 2.0 degree tiles. The coastline used in the DEM is based on the High Water Line extracted the largest scale Electronic Navigational Chart (ENC) available for a given area, edited to be contiguous and attributed by height extracted from the Vertical Offshore Reference Frame (VORF). A vector coverage layer indicating the provenance of the source data used to create the DEM is supplied and a confidence grid is available on request.",
