Question

What does spectral resolution refer to in remote sensing?

• A. Ability to detect different wavelengths of electromagnetic radiation
• B. Ability to distinguish between different features on the ground
• C. Ability to capture images at various times
• D. Ability to discern details within an image

Hint:

Spectral resolution is about wavelength discrimination, not spatial or temporal resolution.

Answer 1

The Correct Option is A

Spectral resolution defines a sensor's ability to distinguish between different wavelengths of the electromagnetic spectrum. Higher spectral resolution allows better discrimination between different materials based on their spectral signatures.
