Brian,
You could try gdalbuildvrt, then gdalwarp that with -of VRT, then tile it
how you like with gdal_translate. I think that gdal_retile.py has some options
to do what you want as well.
I think that the slivers are probably because the projections have
different angles of rotations and pixels may not be exactly square in each
projection and may not map from one to the other cleanly. Making a mosiac
first (even if virtual) deals with this (or at least pushes it to your edges
where you won't notice it.
HTH, Eli

Hi All-
I have a series of tiffs, georef'd in 4326, which side by side cover
>1000 km at latitude 38
California from the coast past the borders
I warped them all to 3310 using gdalwarp with default settings..
However, the resulting images appear to leave a sliver between them
In other words, they are *not* complete coverage of the area covered
in the original tiffs. This is unexpected to me..
Is this expected results?
How can I be sure to get complete coverage in the resulting set of
re-projected tiffs?
thanks
-Brian
