I have tried it both with and without reprojection, to the same effect. > - are all your granules of the same resolution? Yes, they are all 0.15m pixels in 5000x4000 images. I have tried both leaving the existing 0 level images at 5000x4000 (-pyramidOnly) and retiling to 2048x2048, both with the same result.
