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.
