Question

A Hyperspectral sensor is characterized by:

• A. Small number of wide spectral bands
• B. Large number of narrow, contiguous spectral bands
• C. Only thermal infrared bands
• D. Low spatial resolution only

Hint:

Comparison: \[ \boxed{ \begin{aligned} \text{Multispectral} &\rightarrow \text{Few broad bands} \text{Hyperspectral} &\rightarrow \text{Many narrow contiguous bands} \end{aligned} } \]

Answer 1

The Correct Option is B

Concept: Hyperspectral sensors record reflected or emitted radiation in hundreds of narrow, contiguous spectral bands. This enables detailed identification of materials based on their spectral signatures.

Step 1: Understand hyperspectral sensing. Unlike multispectral sensors, hyperspectral sensors acquire data in many closely spaced wavelength bands.

Step 2: Identify the defining characteristic. Hence, \[ \boxed{\text{Hyperspectral sensors have a large number of narrow, contiguous spectral bands}.} \] Therefore, the correct option is \[ \boxed{(B).} \]
