A line of sight taken to any point to determine its elevation is called:

There are two points, A and B, whose elevations above datum are h4 = 1380 ft and hp = 930 ft. and whose images a and b on a vertical photograph have photo coordinates a = 2.95 in.. y = 2.32 in. z = -1.64 in., and 3 = -2.66 in. The camera focal length was 152.4 mm and the flying height above datum 7800 ft. Part A On the same photograph, an image d of a third point D appears. Its elevation is hp 1290 ft and its photo coordinates are zd=2.72 in. and yu = 3.09 in. Calculate the area, in acres, of triangle ABD Express your answer to four significant figures.
