[Termes IGN] World Geodetic System 1984Résumé : (auteur) This paper reviews various types of distances as they are measured and derived in all the various coordinate systems used by surveyors. Unlike measurements made with transits and levels that are oriented according to gravity and are traditionally considered to be horizontal and vertical, respectively, GPS measurements are inherently three-dimensional and not oriented to the geoid in an obvious way. GPS measurements are placed into a geographic context by the use of mathematical reference ellipsoids and geodesy computations. Opto-mechanical measurements must be reduced to become geodetic quantities. The GPS and opto-mechanical instruments operate in intrinsically different worlds and only can be reconciled by rigorous application of the principles of geodesy. This paper reviews the issues, the fundamental principles, the reductions and geodetic computations, and presents a real-world measurement campaign showing how to reconcile total station and GPS measurements.
