Data for 2000 were supplied by BODC. The values were supplied to BODC via the University of Cape Town and so are not being classed as official.

Following the supply of data from the South African Hydrographic Office the data for the year 2000 has now been revised with the official values.
=========================== FOLLOWING PSMSL DOCUMENTATION ADDED 24-Sep-2009
Heights of chart datum relative to land levelling
datum in South Africa and Namibia: Saldanha
Datum: up to 31st Dec 1978 = -0.582
Datum: 1st Jan 1979 - 31st Dec 1997 = -0.900
Datum: 1st Jan 1998 - 31st Dec 2002 = -0.975
Datum: 1st Jan 2003 onwards = -0.865
Datum is now LAT so unlikely to change.
