Normalhöhennull ("standard elevation zero") or NHN is a vertical datum used in Germany. In geographical terms, NHN is the reference plane for the normal height of a topographical eminence height above mean sea level used in the 1932 German Mean Height Reference System (Deutsches Haupthöhennetz). The plane is in the shape of a quasi-geoid.
Normalnull ("standard zero") or Normal-Null (short N. N. or NN) is an outdated official vertical datum used in Germany. Elevations using this reference system were to be marked Meter über Normal-Null (“meters above standard zero”). Normalnull has been replaced by Normalhöhennull (NHN).
Amsterdam Ordnance Datum or Normaal Amsterdams Peil (NAP) is a vertical datum in use in large parts of Western Europe. Originally created for use in the Netherlands, its height was used by Prussia in 1879 for defining Normalnull, and in 1955 by other European countries.
Das Normalhöhennull (NHN) ist die Bezeichnung der Bezugsfläche für die Angabe von Höhen über dem Meeresspiegel in Deutschland. Es ist seit 1993 der Nachfolger des 1879 eingeführten Normalnull (NN).

In contrast, the zero level surface of the normal heights since 1992 (DHHN92, DHHN2016) is refered to as Normalhöhennull (NHN). It is realized by quasigeoid models (DHHN92: GCG05/GCG2011, DHHN2016: GCG2016).
