heighting
Heighting is a term used in several technical fields to describe the determination or adjustment of heights, typically with reference to a standard vertical datum such as mean sea level or the geoid. In surveying and geodesy, heighting refers to establishing the vertical position of points by measuring height differences relative to a known benchmark. Common methods include spirit-leveling and differential leveling to obtain orthometric heights, and trigonometric heighting, which uses measured distances and vertical angles to calculate height differences from a baseline. Modern practice may supplement or replace traditional leveling with GNSS-based heighting, which uses global navigation satellite systems and geoid models to estimate height relative to a reference ellipsoid or a corrected geoid model.
In geographic information systems and cartography, heighting is the process of assigning vertical coordinates to terrain
Heighting also appears historically in surveying literature as a general term for height transfer or height
