Hello, This has actually been resolved. I just haven't got back here to give an update until now.
The proper mapserver use case for ENVI type rasters and WCS will be posted at mapserver.org by Frank Warmerdam once I get my 'stuff' together. There are some small sample ENVI test files available at: http://filebin.ca/cpaux/ENVI_test_files.ZIP NOTE: the files listed as ...int32... are actually ...int16... and the file name is a typo. These files (content) are not scientific data files but 6 band binary files with headers. The image data is a text burn in of the band number in each band on a zero background. The problem I was having with my WCS dataset LAYER definition seemed to clear up with some minor editing. There is a sample map file for UMN mapserver and ENVI format WCS located at: http://filebin.ca/upkmxs/mapfile.txt The geographic pixel size in the map file is incorrect. It should be 2.8125 degrees not 0.08333. The file is only 128x64 spatially. the band selection for GetCoverage URL is &bands=<number> ie:(see end of URL line) http://somewcsserver.net/cgi-bin/wcs?REQUEST=GetCoverage&SERVICE=WCS&VERSION=1.0.0&COVERAGE=BOGUStestData&CRS=EPSG:4326&BBOX=-180,-90,180,90&WIDTH=128&HEIGHT=64&FORMAT=GEOTIFF_FLOAT&bands=6 Hope that's useful. If you need NDVI that's a whole other story. :) Peter Lime, Steve D (DNR) wrote:
Any chance of getting a test dataset? -----Original Message----- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Peter Willis Sent: Monday, February 08, 2010 12:37 PM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] Continuing problem with WCS and ENVI Multi-band files Hello, I continue to have a problem selecting a single band from a multi-band (563 bands) ENVI format BSQ file. Using the following URL mapserver gives me a FLOAT32 GTiff file but it is always filled with zeros. http://wcs.foo.com/cgi-bin/wcs?REQUEST=GetCoverage&SERVICE=WCS&VERSION=1.0.0&COVERAGE=NDVI&CRS=EPSG:4326&BBOX=-135,55,-121,46&WIDTH=256&HEIGHT=256&FORMAT=GEOTIFF_FLOAT&Band=122 Is there any documentation that clearly shows how WCS can be set up to do this? My current LAYER definition is as follows: LAYER NAME VegetationIndex STATUS OFF DEBUG ON TYPE RASTER METADATA "wcs_label" "Data/NDVI" "wcs_rangeset_name" 'bands' "wcs_rangeset_label" "NDVI" "ows_extent" '-135 55 -121 46' "wcs_resolution" '0.08333333333333332 -0.083333333333333332' "ows_srs" 'EPSG:4326' "wcs_srs" 'EPSG:4326' "wcs_formats" 'GEOTIFF_FLOAT,GEOTIFF_INT16' "wcs_nativeformat" 'ENVI' END DATA /NDVI/ndvi.img PROJECTION "init=epsg:4623" END DUMP TRUE END
