ortometriseen
Ortometriseen is a Finnish term that can be translated to "orthometric" in English. It refers to the measurement of height relative to a geoid, which is an idealized mean sea level surface. This is in contrast to ellipsoidal heights, which are measured relative to an ellipsoid of revolution, a simpler mathematical model of the Earth's shape.
Orthometric heights are crucial in many scientific and engineering applications. For instance, they are used in
The calculation of orthometric heights typically involves using the ellipsoidal height obtained from GPS measurements and
