Greetings. I have noticed a difference in gdal_translate vs gdalwarp. gdal_translate introduces a slight bias when it resamples. This seems to be reproducible when coarsening resolutions by roughly 5-10 percent.
For my specific example, I'm starting with a .5m x .5m UTM image. I've seen this in GDAL 2.41 and 3.1.4. I perform the following calls: gdal_translate -r cubic -tr .53 .53 src.tif src_TRANSLATE.tif gdalwarp -r cubic -tr .53 .53 src.tif src_WARP.tif It's hard to quantify the amount of shift, but I would approximate it to be about a third of a pixel. I believe gdalwarp is more rigorous than gdal_translate. However, I wouldn't expect a visible shift with the latter. The question is, is this expected behavior or a bug? I have some animated gif's illustrating the problem. These will obviously go away after some time. gdal_translate src.tif vs src_TRANSLATE: https://drive.google.com/file/d/1XeWafUlUzN6somcyUL2dfyvlwS3IOpRP/view?usp=sharing gdalwarp src.tif vs src_WARP: https://drive.google.com/file/d/1Zv5ypaRzCEZzVUmfGf01UtTTVoPD7ADL/view?usp=sharing Thanks in advance, Mike
