Making observations, in leveling, in such a way that distances to the two levelling rods are approximately equal. Also referred to as balancing lines of sight and balancing backsight and foresight ...

Vertical angulation

Earth science; Mapping science

The process of obtaining differences of elevation by means of observed vertical angles together with lengths of lines. In geodesy, vertical angulation is called trigonometric leveling.

Barlow levelling rod

Earth science; Mapping science

A self reading levelling rod on which graduations are marked by triangles each 0. 02 foot in height. The Barlow levelling rod is no longer in general use.

Fiducial axis

Earth science; Mapping science

The line joining two opposite fiducial marks on a photograph.

Aposphere

Earth science; Mapping science

A surface of rotation whose meridional section is defined by the equation r = a sech(b ( Ψ + c)), where a, b and c are constants, Ψ is the isometric latitude and r is the perpendicular distance ...
