geodetic measurement

A geodetic measurement is any method of measuring geographic distance or area that uses a curved (nonplanar) surface to model the Earth. The most common of these use a great circle or a geodesic line. This is in contrast to a planar measurement, which cut through the surface of the earth to provide measurements.
