koordinaatiotason

Koordinaatiotason is a term used in the field of geodesy and cartography to describe a reference surface or datum to which geographic coordinates are related. It serves as a framework for measuring and representing the positions of points on the Earth's surface. The most commonly used koordinaatiotason is the World Geodetic System 1984 (WGS84), which is widely adopted for GPS and global mapping applications. Other regional koordinaatiotason include the European Terrestrial Reference System 1989 (ETRS89) for Europe and the North American Datum 1983 (NAD83) for North America. These systems are essential for ensuring consistency and accuracy in geographic data, enabling precise navigation, surveying, and mapping activities. The choice of koordinaatiotason is crucial for avoiding errors and discrepancies in spatial data, as different systems can result in significant differences in coordinate values.
