UKHO Marine Hydrographic Charts 1771-1 and 1771-2

This product has been derived in part from material obtained from the UK Hydrographic Office with the permission of the UK Hydrographic Office, Her Majesty’s Stationery Office and other relevant authorities. Charts are mostly standardised to the WGS84 Datum, especially in UK waters, and are projected either to Mercator or Transverse Mercator. All depths and drying heights are referenced to Chart Datum, which approximates to Lowest Astronomical Tide (LAT). The nominal scale for each chart is 1771-1 (1:125000) and 1771-2 (1:15000). Note that in 2015, work done in St Helenas waters resulted in possible update to the charts. (1771-1 EPSG:54004)
