- Increased radiometric resolution
- Continuous global coverage
- Higher spectral resolution
- Revisit flexibility and stereoscopic mapping
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
SPOT satellites have steerable sensors that can be tilted away from the nadir direction.
This capability allows imaging of the same area from different viewing angles and increases revisit opportunities.
Step 1: Understand off-nadir pointing. Sensor tilting enables
• Faster revisit of a target area.
• Stereo image acquisition.
• Generation of Digital Elevation Models (DEMs).
Step 2: Identify the primary advantage. Hence, \[ \boxed{\text{Off-nadir viewing enables revisit flexibility and stereoscopic mapping}.} \] Therefore, the correct option is \[ \boxed{(D).} \]
