<br></div>You may also consider adding tiling with "-co TILED=YES" to the previous command:<br><div><div><div><div><div><div>"gdal_translate -b 1 -b 2 -b 3 -co TILED=YES inputTiff outputTiff"<br><br></div>
<div>Default tiling is 256x256; you may specify different one with -co BLOCKXSIZE=nnn -co BLOCKYSIZE=mmm<br></div><div><br>Hope this helps.<br>Cheers,<br>Daniele<br></div><div><br></div></div></div></div></div></div></div>
