Photogrammetry MCQ with answer and solution

Concept

Lens coverage angle in aerial photogrammetry

Formula

NONE

Step-by-step solution

1. Lenses for aerial photogrammetry are categorized according to their angular field of view. 2. Wide-angle aerial photogrammetric lenses provide an angular coverage of approximately 93 degrees. 3. A maximum coverage angle of 93 degrees optimizes the ground area captured per aerial frame. Answer: A

Explanation

Standard wide-angle aerial camera lenses used in photogrammetric mapping are engineered to cover a large field of view across the film format. These wide-angle lenses typically provide a maximum angular field of view around 93 degrees along the diagonal.

Why the other options are wrong

B) A 63° coverage capacity corresponds to normal angle aerial photogrammetric lenses. C) A 53° coverage angle is typical for narrow angle aerial camera lenses. D) Super wide-angle lenses reach up to 120°, whereas wide-angle lenses reach around 93°.

Shortcut

Wide-angle aerial photogrammetry lenses cover up to 93° field of view.

Common mistake

Confusing wide-angle aerial photogrammetry lens coverage with normal-angle lens coverage angles.
