problem invoking WCS: "no template"???

[Piero Cavalieri]

This one works for me (not sure if it's formally correct, but it seems to work):

http://pcavalieri/Scripts/WCS/mapserv.exe?map=D:/gis/data/trentino/trentinoWCS.map&SERVICE=WCS&version=1.0.0&REQUEST=GetCoverage&Coverage=ECW&BBOX=1650000,5095000,1700000,5100000&CRS=EPSG:26591&RESX=1&RESY=1&FORMAT=ECW

and .map:

#
# Start of map file
#
NAME TRENTINO
STATUS ON

OUTPUTFORMAT
    NAME ECW
    DRIVER "GDAL/ECW"
    MIMETYPE "image/ecw"
    IMAGEMODE "BYTE"
    EXTENSION "ecw"
END

#
# Start of layer definitions
#
LAYER
  NAME "ECW"
  TYPE RASTER
  STATUS OFF
  PROCESSING "SCALE=AUTO"
  UNITS Meters
  DUMP TRUE
  TILEITEM "location"
  TILEINDEX "D:\gis\data\trentino\ECWindex.shp"
  METADATA
    "wcs_description" "ecw"
    "wcs_name" "ecw"
    "wcs_label" "ecw trentino"
    "ows_srs" "EPSG:26591"
    "ows_extent" "1609350 5056766 1731630 5159006"
    "wcs_resolution" "1 1"
    "wcs_bandcount" "3"
    "wcs_formats" "ECW"
  END
END


END # Map File

Cheers
 Piero

Jeff,

What does your request URL look like?  Did you include service=WCS in
the request?
