The (vertical) datum is a reference plane for the elevations of, for instance, the terrain, water levels and buildings. It forms a baseline to which all elevations can be related, thereby creating an internally consistent representation of relative heights.
The most commonly used datum in the Netherlands is the NAP or Amsterdam Ordnance Datum (Dutch: Normaal Amsterdams Pijl) and this is the datum which is currently used in the Tygron Platform.
