Question

Which of the following imagery can facilitate delineation and identification of local reliefs?

• A. \(\text{Ortho imagery} \)
• B. \(\text{Stereo imagery} \)
• C. \(\text{PAN imagery} \)
• D. \(\text{Geocoded imagery} \)

Hint:

Stereo imagery is used for 3D terrain modeling, elevation mapping, and relief feature identification.

Answer 1

The Correct Option is B

Step 1: Understanding stereo imagery. - Stereo imagery consists of two or more images taken from different angles, allowing 3D visualization of terrain and relief features.
Step 2: Explanation of incorrect options. - Ortho imagery a.: Provides geometrically corrected 2D images, unsuitable for relief identification. - PAN imagery c.: High-resolution panchromatic images, but does not provide depth perception. - Geocoded imagery d.: Has spatial reference but does not offer 3D relief details.
Step 3: Selecting the correct option. Since stereo imagery enables 3D terrain visualization, the correct answer is b. Stereo imagery.
