transittheodolites
A transit theodolite is a type of EDM (Electronic Distance Measurement) device used in geodetic surveying to measure the distance and direction between two points. It is a hybrid instrument that combines the functionality of a theodolite, which measures horizontal angles and vertical angles, with a transit, which is a rotating beam that shines a beam of light over the observation points.
Transit theodolites are used to determine the relative position of a series of reference points on the
Transit theodolites generally consist of an inner transit telescope, an outer telescope, and a rotating circle.
Typical components of a transit theodolite include an optical telescope, a leveling system to ensure accurate
