Hi,
I used gdal-translate command to downsample a nitf file, but the size of
generated file almost doubles. Is there something that I did wrong? I can't use
this new file because bigger size is not acceptable, even though its display
looks correct.
Here is the command I used:
C:\Map\RPF\CIB
OK, looks like [3] for me. Thanks.

Thanks for the reply. I had looked at these before, and then looked
again after your note, but I just don't understand how I map the climate
variable values to different colors in the palette, along the lines of:
tmax < 30| color1

tmax > 50| c
Hi,
Hopefully this is a quick one, I think the answer's so obvious I'm
missing it. I'm trying to use GDAL to create a TIFF copy of a NITF
file. I've downloaded and compiled 1.8.1 (under Windows) and used
gdal_translate from the command line to create the copy. I can view the
new file from I
I thought I'd tried that and it failed, but it looks to be just a problem of
