Q. An aerial photograph of a terrain having an average elevation of 1400 m is taken at a scale of 1:7500. The focal length of the camera is 15 cm. The altitude of the flight above mean sea level (in m, up to one decimal place) is _
Ans: 2520 – 2530
Sol:
Average elevation (h) =1400 m, focal length (f) = 15 cm, scale (S) = 1:7500
Let the altitude of the flight above mean sea level be ‘H’
