The boundary-value problem in physical geodesy can be solved by Stokes's well-known formula for the anomalous gravity potential, with geoidal height calculated through Bruns's formula. The geoid represents a vertical datum for orthometric heights used in many countries and an accurate geoid is also of interest to many other geophysical ...

An elevation above the geoid is defined as an orthometric height. GPS receivers cannot produce orthometric heights directly but they produce heights relative to the WGS 84 ellipsoid. Elevations determined by GPS are called ellipsoidal (or geodetic) heights.

Sometimes the height of a point above “sea level” – orthometric height (above the geoid), or normal height (above the quasigeoid) – shall be used in addition to the ellipsoidal height. In the sequel, disturbing potential will be denoted by , actual gravity by , normal gravity by , and geoidal height by .

However, orthometric heights or geopotential numbers are free from the lacks above, thus, all leveling can be calculated strictly in the usual. way, replacing leveled height differences by geopotential or orthometric height differences. From (3) orthometric heights can be computed from geopotential numbers, and vice versa.

Geoidal height; Stokes’s formula; ellipsoidal correction. Introduction. The determination of the geoid is a basic task of physical geodesy. The approaches used to determine the geoid are usually classified into the model approach and the operational approach (Moritz, 1978). Stokes’s formula is playing a key role in the model approach.

The height difference between each spot height is calculated and used with the horizontal distance between them to calculate the position on the line joining the spot heights at which the required contour is located. 6.2.7 Use of contour maps. Contour maps are used in obtaining sections (i.e. cross sections and longitudinal sections).
