MapServer WMS : Geotiff Float 32

[Fabio D'Ovidio]

Hi !

I'm working with ESRI GRID raster and I have exported it in GeoTiff.
Now, I have configured MapServer as WMS to render it. The problem is that I am not able to 
download GeoTiff from MapServer and display each pixel float value.


Is this possible with a WMS ? Have I use a WCS configuration for this purpose ?

This is the map file :

MAP
  NAME "Preview"
  STATUS ON
  EXTENT 1.67416e+006 4.82883e+006 1.68398e+006 4.83571e+006  SIZE 800 600
  IMAGETYPE gtiff
  IMAGEQUALITY 100  
  WEB
    # path relative to the webserver document root
    IMAGEPATH "C:/inetpub/wwwroot/temp/"
    # full path to image tmp dir, so cgi can find it
    # Note: Windows is much happier with a full path here.  Unixes might get away with path 
relative to cgi-bin.
    # Use backslash "\" with Windows, forward-slash "/" with Unixes, and end the path with 
the proper slash.
    IMAGEURL "./temp/"
