The distance in the x direction between two control points on a vertical aerial photograph is 5 3 in If the distance between these same two points is 4 0 in on a second photograph having a scale of 1 24 000 determine the scale of the first vertical aerial photograph scale 1 Your response is within 10 of the correct value This may be due to roundoff error or you could have a mistake in your calculation Carry out all intermediate results to at least four digit accuracy to minimize roundoff error If the focal length of the camera is 6 in and the average elevation at these points is 130 ft determine the flying height in ft from which each photograph was taken X first photograph elevation Your response is within 10 of the correct value This may be due to roundoff error or you could have a mistake in your calculation Carry out all intermediate results to at least four digit accuracy to minimize roundoff error ft 12100 ft second photograph elevation
