1. Is it possible to set up a raster layer for delivering 7-band imagery in GeoTIFF/img formats? If it is, how? I tried with setting "wcs_bandcount" "7" in the LAYER METADATA, but that lead to error message saying that band count can not be higher that four. The NetCDF example I found from the use case document makes me think that it might be possible with some 'wcs_rangeset' settings.
Jukka, I suspect the problem relates to the selection of output format. MapServer pre-declares an output format called "GTiff" which is an RGB (or possibly RGBA) mode output format. It also has the mime type "image/tiff". I suspect you are selecting the format image/tiff via WCS and getting that built in declaration instead of your own with the all important "BYTE" imagemode. My suggestion is either to use the name "GTIFF" for your outputformat declaration (pre-empting the built in one) or select the GeoTIFF output format by name instead of mimetype.
2. Does layer PROCESSING directives have any effect with WCS? I was trying to select certain bands from 7-band imagery by setting for example PROCESSING "BANDS=7,4,2" in LAYER definitions, but I received always just band combination 1,2,3. In this case I used "wcs_bandcount" "3". In addition to BANDS I would like to use also LUT and RESAMPLE options with WCS.
I believe the bands selector is superceeded by the bands selected in the WCS call. Resampling types "NEAREST" and "BILINEAR" should be support via WCS but have to be passed in via the WCS request. I don't think you can establish defaults in the mapfile. I suspect the LUT operations are processed only in the image modes other than "pure data". That is, IMAGEMODE BYTE likely precludes their use as things stand. I could look at altering this if you wanted.
3. I have used wget for downloading from my WCS service and it works fine. I had installed one 'real' WCS client but it did not like my MapServer WCS service. Are there some WCS clients that are known to work well with MapServer WCS?
wget is *my* favorite WCS client. GDAL is also a WCS client, and should work fairly well with MapServer.
