Normalnull ("standard zero") or Normal-Null (short N. N. or NN) is an outdated official vertical datum used in Germany.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 Normalnull has been replaced by Normalhöhennull (NHN).
The analysis highlights History and Standards as prominent areas in the source structure around Normalnull.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
