A surveyor initial ought to know the horizontal length in between two with the objects, known as the baseline. Then the heights, distances and angular placement of other objects is usually derived, assuming that they are noticeable from considered one of the original objects. Higher-accuracy transits or theodolites had been employed, and angle measurements were being recurring for amplified precision. See also Triangulation in a few Proportions.
Triangulation is actually a means of horizontal locale favoured in the days just before EDM and GPS measurement.
