Brent,
Have you tried with GDAL 1.6.0 beta ? Much work has been done in that area and
those artifacts should have disappeared and people. See

Has anyone experienced resampling artifacts using gdalwarp?
I'm using v1.5.2, and with lanczos or cubicspline resampling, I get a
vertical line and a horizontal line of seemingly random pixels about 6
pixels wide running through the center of the output image.
I'm resampling a 16-bit tif image from 12.5 meters to 200 meters. The
other resampling methods result in an ok output image.
I've attached a png to illustrate the effect. I thought I'd ask before
filing a bug report...
Thanks!
Brent Fraser
