Referenzhöhe

Referenzhöhe is a German term that translates to "reference height" in English. It is a concept used in various fields, particularly in surveying, engineering, and aviation, to establish a standardized elevation against which other heights are measured. The specific datum used for a reference height can vary depending on the context and the region. For instance, in surveying, a reference height might be linked to a national geodetic datum, which is a precisely defined reference point for a country's coordinate system. In aviation, reference heights are crucial for defining altitudes and ensuring safe separation between aircraft. These can be based on mean sea level or other standardized atmospheric pressure levels. The purpose of a reference height is to provide a common and unambiguous baseline for height measurements, preventing confusion and errors, especially when coordinating across different projects or systems. Without a defined reference height, the meaning of any given elevation would be subjective and unreliable.
