2 Δεκ 2023 · A height system is a one-dimensional coordinate system used to express the metric distance (height) of a point or object above a reference surface (i.e. the zero-height surface) along a well-defined path. The metric distance is also known as vertical coordinate, elevation or altitude.
1 Ιαν 2021 · Height or elevation of a point P on the Earth’s surface is the distance from P to a reference surface of zero height, measured along a precisely defined path. Different Height Systems result from the choice of the reference surface and the path from P to that surface.

A height system is a one-dimensional coordinate system used to express the metric distance (height) of a point above a reference surface (i.e., the zero-height level) along a well-defined path.
3 Μαρ 2017 · This paper addresses the theoretical foundations supporting the implementation of such a physical reference surface in terms of an International Height Reference System and provides guidance for the coming activities required for the practical and sustainable realization of this system.
A vertical geodetic datum is the practical realisation of a height system and its reference surface for users, nominally tied to mean sea level. In Australia, the normal-orthometric height system is used, which is embedded in the Australian Height Datum (AHD).
