Q.90
The actual pixel value is retained in which method of resampling?
- Nearest Neighbour Interpolation: Resampling technique in digital remote sensing that assigns the Digital Number (DN) of the closest pixel center in the input image to the output grid without numerical averaging or modification. Because original pixel values are strictly preserved, it is preferred for categorical thematic classification.
- Bilinear & Cubic Interpolation: Alter DN values by distance-weighted averaging across 4 and 16 adjacent pixels, respectively. (Correct answer: Option 1)
