What is my datum level?

A Datum Level is an arbitrary horizontal plane on a construction project used as a reference point for all other vertical dimensions to be measured. It is used to highlight differentials between vertical heights of floor levels along with differing levels of two separate points on the site.

What is the difference between chart datum and ordnance datum?

The Ordnance Survey (OS) is Britain's National Mapping Agency and maintains the national vertical datum. A chart datum value is dependant upon the range of the tide at a particular location. It varies from place to place and therefore is not a suitable national reference plane.

What is the land leveling datum?

The vertical datum is sometimes referred to the Land Leveling Datum and is based upon the measurement of mean sea level (MSL) at tide gauges at Cape Town, Port Elizabeth, East London and Durban at the beginning of the 1900's.
