I have a set f tiff files at different zoom levels/resolutions 0.tif (2048x1024) 1.tif (4096x2048) 2.tif (8192x4096) I would like to create one tif that is 8192x4096 but have 2 overviews that are the 0.tif and 1.tif. Is there a GDAL command that I can give multiple tiffs to create one tiff with overviews? Thanks
