WebStadia Tacheometry with Electronic Theodolites. 27. This paper reports results of an experiment carried out as a continuation to those tests. Simple design electronic theodolites with stadia hairs etched on their cross-hair reticules, were, however, used instead of conventional optical theodolites and tacheometers. The principle of tacheometric surveying is based on the property of an isosceles triangle i.e. the ratio of the distance of the base from the apex and the length of the base is always constant. The formula for the horizontal distance is determined using: H= K*s* cos ² θ Note: The additive constant is 0.00, and the multiplying constant is 100.00.
