On the Curvature and Torsion of the Gravity Fieldfrom the generalized formulae of Frenet.where . is a versor such that . form a positive right-handed triad, .. is the first curvature or flexion of the surface in the direction . considered, and .. the geodesic torsion of . in the same direction. The index . characterizes the direction ., for the reason which will later be apparent.

tance measurements to the use of artificial satellites, has been great, and is still largely to be felt. These changes have forced the practitioners of the ancient art of Earth measurement to alter their way of thinking about the space that surrounds us, something fundamentally more difficult than a

Foundations of Intrinsic Geodesy as well as the angle between two distinct arcs. Specifically excluded, however, are all the linear and angular measurements which entail leaving the surface, and as a result, there is no possibility of determining the Cartesian coordinates in space of a point on the surface, nor the direction of the normal to the surface.

Generalized Legendre Expansions in Spaceow the corresponding elements at the other end. It was noted that these expansions have been generalized in various ways by several authors, and there was presented a further generalization for any curve traced out on any surface whatever

The Adjustment of Geodetic Networks in the Three-Dimensional Ellipsoidal Model Space of Somiglianarmore required to be close to observable parameters in the natural geodetic field and the associated metric tensor to be of simple analytical structure. A scale factor may be assigned to account for possible strains induced by the procedure in the metric relations.
