Question

Which of the following is not a hyperspectral sensor?

• A. \(\text{Hyperion} \)
• B. \(\text{HIRS} \)
• C. \(\text{CHRIS} \)
• D. \(\text{HYDICE} \)

Hint:

Hyperspectral sensors collect data in hundreds of bands, while multispectral sensors (like HIRS) capture only a few broad bands.

Answer 1

The Correct Option is B

Step 1: Understanding hyperspectral sensors. Hyperspectral sensors capture data in hundreds of narrow spectral bands, allowing precise material identification.
Step 2: Classification of given options. - Hyperion (NASA, EO-1) - Hyperspectral sensor. - CHRIS (ESA) - Hyperspectral sensor. - HYDICE - Hyperspectral airborne sensor. - HIRS (High-Resolution Infrared Radiation Sounder) - NOT hyperspectral; it is a multispectral sensor used for meteorology.
Step 3: Selecting the correct option. Since HIRS is a multispectral sensor, not hyperspectral, the correct answer is b. HIRS.
