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.
