[Gdal-dev] gdalwarp output

[Ray Joslyn]

Frank,
I could do that however the problem I run into then is that I'm left
having to extract the image at full resolution (since no pixel down
sampling is available in gdal_translate, correct?) which can be quite
memory intensive since gdal_translate also does not have a memory usage
switch to set the amount of memory for caching.

Ray,

Not as things stand.  Rather then wedging a huge amount of complexity
into
gdalwarp I would strongly encourage you to use gdal_translate to cut out
the
band(s) you want before running gdalwarp.  If you need a customized
processing
pipeline you could always write your own modified utility using the
warping
API.  Looking at gdalwarp would be a good start.

Best regards,
