The EDM slope distance between two points is 2,183.71 ft, and the vertical angle is 2º4530 (the vertical angles were read at both ends of the line and then averaged). If the elevation of the instrument station is 285.69 ft and the heights of the instrument, EDM, target, and reflector are all equal to 5.08 ft, compute the elevation of the target station and the horizontal distance to that station.

Photogrammetry

Photogrammetry is a technology of taking measurements of physical objects present in the environment, using photographs. It includes the process of recording and analyzing a three-dimension image in the two-dimension form. Photogrammetry was invented around 150 years ago in 1851 by Aimé Laussedat, he was also known as the father of photogrammetry, but this method was not in use until 50 years after its invention. This method was first used in Germany by Dr. Albrecht Meydenbauer in 1893 who was the director of the Royal Prussian Photogrammetric institute founded by him.
