Hi Chris- Can you send your map file? I've had great success with negative raster values when defining my own classes (Sea temperature GeoTIFF / AAI Grid, for instance).

I can't get any of the pixels with values less than -1 to display in mapserver. I have tried using the processing directive to scale the values and I've tried specifying classes, and neither works. I have also tried different file formats (geotiffs and erdas .img). Anyone know why this isn't working? I'm using mapserver 4.8.3 and gdal 1.3.1 on solaris 10. Thanks for any ideas, Chris
