- On a vertical photograph of flat terrain, the scaled distance between two points is ab. Find the average photographic scale along ab if the measured length along the same line is AB on a map plotted at a scale of Smap for the following data. ab=1.66in.; AB=4.56in.; Smap=1:9600 (Express your answer in feet to four significant figures.) ab=116.04mm; AB=2.23mm; Smap=1:24,000 (Express your answer to three significant figures.)vertical aerial photo is exposed at 3910 ft above mean sea level using a camera having an 88.9 mm focal length. A triangular parcel of land that lies at elevation 850 ft above sea level appears on the photo, and its sides measure 39.5 mm, 28.9 mm, and 27.7 mm, respectively. What is the approximately area of this parcel in acres? 3. On a vertical photograph, image a and b of ground points A and B have photographic coordinates X = -12.68 mm, Ya = 70.24 mm, Xo = 89.07 mm, and yo = 92.41 mm. The horizontal distance between A and B is 1317 m, and the elevation of A and B are 382 m and 431 m above datum, respectively. Calculate the flying height above datum if the camera had a 152.5 mm focal length?Evaluate the causes of errors in surveying, setting out and data transfer.
