Question

Repetitivity of satellite data refers to:

• A. Ability of a satellite to capture images in different spectral bands
• B. Ability of a satellite to revisit and capture data of the same area at regular intervals
• C. Ability of a satellite to capture high-resolution images
• D. Ability of a satellite to cover large areas in one pass

Hint:

Remember: \[ \boxed{ \text{Repetitivity} = \text{Revisit Time} } \] It indicates how frequently a satellite acquires data over the same location.

Answer 1

The Correct Option is B

Concept: Repetitivity (or revisit capability) is the ability of a satellite to observe the same location on the Earth's surface repeatedly after a fixed interval.

Step 1: Understand repetitivity. It is useful for
• Monitoring crop growth.
• Detecting environmental changes.
• Disaster management.
• Land-use change analysis.

Step 2: Identify the correct definition. Thus, \[ \boxed{\text{Repetitivity is the satellite's ability to revisit the same area at regular intervals}.} \] Therefore, the correct option is \[ \boxed{(B).} \]
