Aerial photography is to be taken of a tract of land that is X-mi square. Flying height will be H ft above average terrain, and the camera has focal length f. If the focal plane opening is 9 × 9 in., and minimum sidelap is 40%, how many flight lines will be needed to cover the tract for the data given below? X = 9; H = 4100 ft; f = 152.40 mm Express your answer as an integer. IVE ΑΣΦ. 11 vec 100 wwwww Peny ?

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.
