Significance of Undulation
Undulation, in environmental sciences, is the difference between ellipsoidal and orthometric height. Knowing undulation is crucial for determining orthometric height from measurements. This value represents the variation between the geoid, a model of mean sea level, and the reference ellipsoid, a mathematically defined surface approximating the Earth's shape. Accurate determination of orthometric height, or height above sea level, relies on understanding and accounting for undulation.
