Orthometric height is a measure of the height of a point above the mean sea level, taking into account the gravitational field of the Earth. It is determined using a geoid model, which represents the shape of the Earth as influenced by gravity. This height is important for various applications, including geodesy, surveying, and navigation. Unlike geometric height, which is simply the distance from a point to a reference surface, orthometric height provides a more accurate representation of elevation in relation to sea level. This makes it essential for understanding topography and for ensuring precise measurements in fields such as engineering and environmental science.
