Hi Ghislain,

you could try increasing the "SAMPLE_STEPS" warp option, e.g.

	gdalwarp -wo "SAMPLE_STEPS=210"

which should improve the localization of the source bounding

Choosing SAMPLE_STEPS as a divisor of the source datasets x-resolution
should help avoid this discretization artifact altogether.
