[Geomoose-users] Query a Mapserver raster group

[James Klassen]

Looks like the fake template trick doesn't work with raster layers.  So it
seems it needs an empty template file.  The following works for me:

Mapfile:
  LAYER
    NAME "query"
    GROUP "all"
    STATUS ON
    TYPE RASTER
    DATA 'raster-query.tif'
    TEMPLATE "template.html"
    TOLERANCE 0
    OPACITY 0
  END
  LAYER
    NAME "raster"
    GROUP "all"
    STATUS ON
    TYPE RASTER
    DATA 'raster-display.tif'
    TEMPLATE 'dummy.html'
  END

template.html:
<!-- MapServer Template -->
<div>
<b>RGB:</b>[value_list]
</div>

dummy.html:
<!-- MapServer Template -->
