[Gdal-dev] gdal_merge vs. gdalwarp

Hi,

I have found in comparing the speed between gdal_merge and gdalwarp that
gdal_merge mosaics tiles together more than twice as fast.  If all I need to
do is mosaic tiles together that are the same resolution and keeping the
same projection, then what advantage is using gdalwarp?  Also I noticed what
I think is a new utility on the gdal utilities page called
"nearblack<http://www.gdal.org/nearblack.html>- Convert nearly
black/white borders to exact value."

Thanks,
