Mixel refers to:
Show Hint
Mixels (Mixed Pixels) are common in remote sensing images with coarse resolution, where a single pixel contains spectral information from multiple land covers.
Updated On: Feb 27, 2025
- \(\text{Combination of two or many pixels} \)
- \(\text{Combined value for the same pixel at different bands} \)
- \(\text{Combined reflection values from different land cover features} \)
- \(\text{Combined reflection atmospheric effect with land cover features} \)

The Correct Option is C
Solution and Explanation
Step 1: Understanding the concept of a mixel.
A mixel (mixed pixel) is a pixel in an image that contains contributions from multiple land cover types instead of representing a single distinct class.
Step 2: Explanation of mixed pixels. - In low-resolution satellite images, a pixel may cover multiple land cover features, causing a mix of spectral signatures. - This mixing leads to spectral unmixing techniques being used to separate components.
Step 3: Selecting the correct option. Since mixels contain combined reflection values from different land cover features, the correct answer is c. Combined reflection values from different land cover features.
