A surveyor is measuring distances in a level yard near a road. A fence post is due north from the surveyor and is 18.0 m away from him. A street sign is to the right of the fence post from the surveyor's view and is a distance of 24.6 m from him. The surveyor measures the angle between the fence post and the street sign to be 22.2°.   (a) What is the distance (in m) between the fence post and the street sign?   (b) What is the angle (in degrees) between the surveyor and the street sign, as measured from the position of the fence post? Hint: Draw a top-down view of the situation.   (c) What is the angle (in degrees) between the surveyor and the fence post, as measured from the position of the street sign?

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.
