Hi Frank, I can (I'll send it to you off-list on Thursday), but the problem appears to be different. I overlooked the fact that the classification is being done in Mapserver (about 30 classes), but even with scalebuckets set I can't get it to speed up. Best regards, Bart Frank Warmerdam wro

Matt, NTFS compression is typically implemented for generic data. On the other hand, the raster compression algorithms do it based on the heuristics of the image data. It is bound to be better. You will even have an option of choosing how lossy the compression should be with these algorithms. Tiff
