[gdal-dev] GDAL Utilities: Keeping output format identical to input format

[Zoltan Szecsei]

Hi,
I've got a few GeoTiffs which have malformed projection/CRS data in them.
I also have ones with the correct data in them.

I would like to replace the malformed projection info with the correct 
one, _without having the original bands re-sampled in any way whatsoever_.
If I use gdal_translate -a_srs +proj="tmerc wadda wadda" tiffbad 
tiffgood, is there a way to keep the bands identical to the input tiff file?
(Maybe someone has written a utility to strip this info out of a 'good' 
image, and set it for use in gdal_translate?)


In a similar vein, using gdaladdo to build pyramids does leave the 
original bands untouched and simply adds the newly calculated overviews 
to the tiff image, does it not?

TIA,
Regards,
Zoltan
