Höhenreferenzsysteme
Höhenreferenzsysteme, or height reference systems, are frameworks used to measure and describe the elevation of points on the Earth's surface. These systems are crucial for various applications, including geodesy, cartography, and engineering. They provide a standardized way to compare and communicate elevation data, ensuring consistency and accuracy across different projects and regions.
There are two primary types of height reference systems: geodetic and normal height systems. Geodetic height
Normal height systems, like the Normalhöhennull (NHN) in Germany, use a geoid model instead of an ellipsoid.
The choice of height reference system depends on the specific requirements of the project and the desired
