2. Do problem 10-2 in the text.
3. Do problem 10-3 in the text.
4. Do problem 10-4 in the text.
5. When a photograph was taken with a lens having a 5.980" focal length, there was
a tilt of 3o 25' and a swing of 165o. The flying height above sea level was 10,030'.
A point A whose elevation is 935' appears on the photograph, and the measured
photographic coordinates of the point are xa=-1.485" and ya=+2.189". Compute the
scale of the photograph at that point.
6. Three points A, B, and C appear on a tilted photograph which was taken from a
flying height of 16,000' above datum with a lens having a 6-in focal length. Their
photographic coordinates are xa=+2.235" and ya=+0.811"; xb=+2.130" and
yb=+3.855"; xc=-2.250" and yc=-3.124". The ground elevations are: hA=672',
hB=250', and hC=970'. Compute the ground survey distances AB, CB, and CA.
The tilt was known to be 3o 15' and the swing was 260o. Compute the horizontal
angle at C from B to A.
7. For a photograph taken with a lens having a focal length of 210 mm, the tilt was
1o 58' and the swing was 85o. Compute the photographic coordinates of the
isocenter and the nadir point with respect to the axis defined by the fiducial
marks.
