korkeusjärjestelmille
Korkeusjärjestelmille refers to height systems or vertical datums used in geodesy and surveying. These systems are essential for defining and measuring elevations above a reference surface, ensuring consistency and accuracy in mapping, construction, and navigation. Different countries and regions often employ their own specific height systems, which can lead to variations in reported elevations.
The fundamental concept behind a height system is the establishment of a zero level, or datum. This
Common types of heights include orthometric height (H), which is the practical height above sea level, and
