I agree with Frank, this sounds like the bug that I reported (and fixed) here: http://trac.osgeo.org/gdal/ticket/2327 (Although it became a log of my alterations to the warper kernel, which was well beyond the scope of the original bug.) ~Seth On Sep 29, 2008, at 11:19 PM, Frank Warmerdam

Hi List, I've hit the same problem twice now, and I'm pretty certain after Round 2 that I'm not introducing it. Basically, I'm using gdal_merge.py to mosaic a group of low-resolution, 32-bit floating point rasters together, then running "gdalwarp -ts xxx yyy -r cubicspline" on the mosaic to get a
