Gravity-Related Height (glossary)
The gravity-related height 'H' is a height that is dependent on the Earth’s gravity field.
Notes to Entry:
- This refers to, amongst others, orthometric height and Normal height, which are both approximations of the distance of a point above the mean sea level, but also may include Normal-orthometric heights, dynamic heights or geopotential numbers.
- The distance from the reference surface may follow a curved line, not necessarily straight, as it is influenced by the direction of gravity.
