Question

Optimal flight planning for a photogrammetric survey should be carried out considering

• A. \( \text{Only side-lap} \)
• B. \( \text{Only end-lap} \)
• C. \( \text{Either side-lap or end-lap} \)
• D. \( \text{Both side-lap as well as end-lap} \)

Hint:

Think of end-lap for forward overlap and side-lap for sideways overlap, both crucial for comprehensive photogrammetric data.

Answer 1

The Correct Option is D

Optimal flight planning for a photogrammetric survey requires careful consideration of both side-lap and end-lap. \begin{itemize} \item End-lap (overlap between successive photographs along the flight line) is essential for stereoscopic viewing and 3D model generation. \item Side-lap (overlap between adjacent flight lines) ensures complete coverage of the survey area without gaps and is also important for creating seamless mosaics and accurate elevation models. \end{itemize}
