What resampling technique does the Geographic Transformer use when reprojecting an image?
The Geographic Transformer uses the nearest neighbor resampling technique. The primary reason is to preserve uniform color depth (palette colors) between the input and output images. This is important due to the fact that other resampling techniques may cause an increase in colors (e.g. 16 to 256, or 256 to several million) thus enlarging the output file size drastically.
