The elevаtiоn оf the оpticаl center of а total station is 877.398 ft. The total station is pointed at a prism placed at the base of a building. A vertical angle equal to 94.6° and a slope distance equal to 166.815 ft are then reported by the instrument. Without changing the horizontal angle, the total station is then pointed at the highest point of the building which is directly above the point where the prism was placed and the vertical angle reading changes to 62.1°.
