[gdal-dev] How remove the piramids from TIFF non-georef

[Daniele Romagnoli]

Hi Andrea,
you may consider using
"gdal_translate -b 1 -b 2 -b 3 inputTiff outputTiff"

I assume you are referring to overviews, right?
In that case, gdal_translate won't copy overviews so you are lucky :)

You may also consider adding tiling with "-co TILED=YES" to the previous
command:
"gdal_translate -b 1 -b 2 -b 3 -co TILED=YES inputTiff outputTiff"

Default tiling is 256x256; you may specify different one with -co
BLOCKXSIZE=nnn -co BLOCKYSIZE=mmm

Hope this helps.
Cheers,
Daniele
