Question

Calculate the relief displacement in a vertical photograph of an object with 200m height at a distance of 5 inches from nadir point taken from an altitude of 7000m.
(a.) 2 inches
(b.) 0.5 inches
(c.) 0.01 inches
(d.) 0.14 inches

Answer 1

Answer:

option 4

Explanation:

Because 200/ 7000 ×5

Answer 2

Answer:

The "relief displacement" in a "vertical photograph" of an object with the given "height" at a distance from the point taken from a  given "altitude" is 0.14 inches.

Option (d.) 0.14 inches.

Solution:

Given,

height (h) = 200 m

Altitude  (a)   = 7000 m

Distance (d) = 5 inches

Formula for Relief displacement= $\frac{h}{a} \times d$

Relief displacement = $\frac{200}{7000} \times 5$

= 0.14 inches

The increase in the elevation, of a feature makes its position on the photograph to be displaced radially outward from the principal point.
