Compute the elevations of points A and B in Problem 27.20.

Problem 27.20:

Similar to Problem 27.19, except the air base is 6940 ft, the flying height above mean sea level is 12,520 ft, the x and y photo coordinates on the left photo are xa = 37.98 mm, ya = 50.45 mm, xb = 24.60 mm, and yb = -46.89 mm, and the x photo coordinates on the right photo are xa = -52.17 mm and xb = -63.88 mm.

Problem 27.19:

An air base of 3205 ft exists for a pair of overlapping vertical photographs taken at a flying height of 5500 ft above MSL with a camera having a focal length of 152.4 mm. Photo coordinates of points A and B on the left photograph are xa = 40.50 mm, ya = 42.80 mm, xb = 23.59 mm, and yb = -59.15 mm. The x photo coordinates on the right photograph are xa = -60.68 mm and xb = -70.29 mm. Using the parallax equations, calculate horizontal length AB.
