Yes, it is. I've told the same to the Geotools guys ;)<br>Nice because during holidays you remembered me about the approach Mapserer uses, and again I was wondering if it will ever be abopted in Geotools... Here it is :)<br>

Btw. today GeoTools/GeoServer guys published a blog post about<br>
improving raster reprojection speed:<br>

<br>
There's also a link to a more verbose 35-page tech report on this<br>
matter. From a brief look it's the same approach as used in MapServer.<br>
