Question

_____ is a raster image resampling technique that DOES NOT alter any of the output cell values from the input raster dataset

• A. \( \text{Nearest neighbor} \)
• B. \( \text{Cubic convolution} \)
• C. \( \text{Bilinear} \)
• D. \( \text{Kriging} \)

Hint:

Remember that nearest neighbor keeps the original data values, which is important for categorical data.

Answer 1

The Correct Option is A

The nearest neighbor resampling technique assigns the value of the nearest input cell to the output cell. This method is the only one among the options that does not alter the original cell values from the input raster dataset. Cubic convolution and bilinear interpolation calculate new pixel values based on the weighted average of neighboring input pixels. Kriging is a geostatistical interpolation technique, not typically used for resampling.
