The scale of the first vertical aerial photograph and the flying height of both the photographs.

Answer to Problem 10P
Explanation of Solution
Given information:
Calculation:
Take two control points on a vertical aerial photograph:
Let the length of DE
We have been given the value of BC
For scale two the value of X is found as follows:
Substituting the values, we get
Now, the value of BC
We have the following formula, for scale first:
Substituting the values, we get
Implying that the scale of the first vertical photograph is
Now, the flying height
Where,
The flying height of the first photograph is,
Now, the flying height
Where,
The flying height of the first photograph is,
Conclusion:
Therefore,the scale of the first vertical photograph is
