As any surveyor should understand, all measurements are in error. We try to minimize error and calculate reasonable tolerances, but error will always be there. Not occasionally; not frequently; always. In the interest of more accurate measurements, we look for better instruments and better procedures.
The theodolite is an instrument for measuring horizontal and vertical angles. It has long had the same general look. A sighting telescope rotates on a vertical axis. A circular scale rotates on this same axis to measure the horizontal angle. A second axis, the trunnion axis, moves with the instrument and is perpendicular to the vertical axis. The trunnion axis allows the scope to pivot up and down, and it has a scale to measure the vertical angle.
This program is basicaly for geomates who will want to generate Theodolite Observation on both faces (L1,L2,R2,R1) from mean external Angles angles.
