Question

End member in hyperspectral remote sensing is known as:

• A. \(\text{Pure Pixel} \)
• B. \(\text{Mixed Pixel} \)
• C. \(\text{Linear Pixel} \)
• D. \(\text{Non-linear Pixel} \)

Hint:

In hyperspectral imaging, pure pixels represent distinct land cover classes, while mixed pixels contain multiple spectral responses.

Answer 1

The Correct Option is A

Step 1: Understanding end members in hyperspectral remote sensing. In hyperspectral remote sensing, an end member is a spectral signature that represents a pure material, meaning it consists of only one class of land cover.
Step 2: Explanation of pure pixels. - Pure Pixel (End Member): Contains a single material's spectral response. - Mixed Pixel: Contains multiple materials, common in coarse-resolution imagery. - Linear/Non-linear Pixels: Terms related to spectral mixing, but not used for end members.
Step 3: Selecting the correct option. Since an end member is a pure pixel, the correct answer is a. Pure Pixel.
