Re: [mapserver-users] How to serve individual RAW binary Bands fromWCS as floating point geotiff
Hello, Interesting... The documentation indicates: RangeSubset=contents:nearest[Band[120]] I tried what you suggest but continue to have the same problem. The mapserver *did not* complain about 'RESAMPLE=BILINEARBand=120' so I guess we can assume that those parameters work.

Re: [mapserver-users] How to serve individual RAW binary Bands fromWCS as floating point geotiff
Hello, Thanks. I have the following line in the map file LAYER declaration: PROCESSING BANDS=120 In any case, the current configuration gives me a floating point geotiff that is all zeros. I know that band 120 of the file has non-zero double precision data in it. Maybe it's a byte ordering problem Peter Lime, Steve D (DNR) wrote: Is this link of help? http://mapserver.org/input/raster.html#special-processing-directives There's a directive to extract a single band from an n-band image...
