korkeusviitejärjestelmät
Korkeusviitejärjestelmät, often translated as vertical datum or height reference system, are established reference surfaces used to define and measure elevations or heights of points on the Earth's surface. These systems are fundamental for various applications, including surveying, mapping, navigation, coastal management, and engineering projects. The primary goal of a height reference system is to provide a consistent and predictable way to quantify how high or low a particular location is relative to a defined baseline.
There are two main types of vertical datums: those based on mean sea level (MSL) and those
Different countries and regions may utilize their own national or local vertical datums. Furthermore, advancements in
