Summary from Deutsch / German Wikipedia (dewiki)

Summary from English Wikipedia (enwiki)

Normalnull ("standard zero") or Normal-Null (short N. N. or NN) is an outdated official vertical datum used in Germany.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 Normalnull has been replaced by Normalhöhennull (NHN).

Summary from Français / French Wikipedia (frwiki)

Normalnull (littéralement « zéro normal » en allemand) était le référent altimétrique en vigueur en Allemagne et dont le niveau zéro correspond au niveau moyen de la mer du Nord. Depuis les années 1990, il a été remplacé par le système DHHN92 (DHHN pour Deutsches Haupthöhennetz : principal réseau altimétrique allemand) basé sur le nouveau référent altimétrique NHN (pour Normalhöhennull). Cependant, la majeure partie des cartes topographiques actuelles donnent toujours des altitudes par rapport à l'ancienne référence.

Summary from Español / Spanish Wikipedia (eswiki)

Normalnull o NN (en alemán ‘nivel cero de altitud’ o 'sobre el nivel del mar') es una expresión que se refiere a un sistema de referencia para las medidas de altitud de los accidentes geográficos en Alemania. En alemán Meter über dem Meeresspiegel o abreviadamente m ü. NN significa 'metros sobre el nivel del mar del Norte', ya que durante el siglo XX se toma el nivel medio del mar del Norte como cero de altitud.

Summary from Nederlands / Dutch Wikipedia (nlwiki)

Normalnull (NN) was van 1879 tot 1992 het referentiepunt voor hoogtemetingen in Duitsland.

Summary from Português / Portuguese Wikipedia (ptwiki)

O Normalnull (NN, "zero normal") foi a medição alemã feita como referência para fazer as medidas ao nível do mar com a sua referência ao mar do norte empregada durante o século XX. No entanto, atualmente é a forma de medir as alturas geodésicas nos mapas topográficos.

Summary from Türkçe / Turkish Wikipedia (trwiki)

Normalnull (NN) Almanya'da 1992 yılına kadar resmî olarak kullanılan deniz seviyesinden yüksekliği gösteren referans noktası ve sistemidir. Konuşma dilinde ortalama deniz seviyesi yerine de kullanılmaktadır.
