Hi Frank, Thanks for the information. I had a couple of questions:
You said below: " I am using the "standalone" FWTools binaries for linux (http://fwtools.maptools.org). In my Apache cgi-bin directory I have the script mapserv_landsat which looks like this: ----------------------- #!/bin/sh export MS_MAPFILE=/home/warmerda/maps/landsat.map . /opt/FWTools-1.0.0a2/fwtools_env.sh exec /opt/FWTools-1.0.0a2/bin/mapserv "$*" " How would the above be revised on a windows system? The exec statement I would replace the /opt with /program files since FWTools is within the "program files" folder on windows. What about the . /opt/FWTools-1.0.0a2/fwtools_env.sh statement? I don't see anything called fwtools_env.sh within the FWTools folder. What is #!/bin/sh is this a linux statement? Thanks, John J. Mitchell On 11/23/06, Frank Warmerdam <[EMAIL PROTECTED]> wrote:

The trick with JPEG2000 and ECW support is getting a binary build for your platform that has these formats included. I have a service at http://maps.gdal.org serving a big south american landsat scene from ecw. I'll provide details on my configuration. You may find it helpful to take a similar approach. I am using the "standalone" FWTools binaries for linux (http://fwtools.maptools.org). In my Apache cgi-bin directory I have the script mapserv_landsat which looks like this: ----------------------- #!/bin/sh export MS_MAPFILE=/home/warmerda/maps/landsat.map . /opt/FWTools-1.0.0a2/fwtools_env.sh exec /opt/FWTools-1.0.0a2/bin/mapserv "$*" ----------------------- This basically invokes the FWTools mapserver executable with a preconfigured mapfile. The FWTools binaries include essentially all required libraries. The mapfile looks like the following and includes sufficient metadat to serve via WMS and WCS. I think there may be a bit of extra cruft in there too. MAP NAME 'LANDSAT' EXTENT -180 -90 180 90 UNITS DD SIZE 600 300 IMAGECOLOR 0 255 0 IMAGETYPE JPEG DEBUG ON PROJECTION "init=epsg:4326" END OUTPUTFORMAT NAME jpeg2000 DRIVER "GDAL/JP2ECW" MIMETYPE "image/jpeg2000" FORMATOPTION "TARGET=95" IMAGEMODE RGB END # # Start of web interface definition # WEB HEADER web/landsatcgi/demo_header.html TEMPLATE web/landsatcgi/demo.html FOOTER web/landsatcgi/demo_footer.html METADATA "ows_title" "Landsat Server" "wcs_label" "Landsat WCS Server" "wcs_keywordlist" "WCS,Landsat" "wcs_onlineresource" "http://maps.gdal.org/cgi-bin/mapserv_landsat"; END IMAGEURL "/tmp/" IMAGEPATH "/u/maps/tmp/" END LAYER NAME "South America" STATUS ON DEBUG ON TYPE RASTER DATA '/home/warmerda/torrents/data/South America Landsat742.ecw' METADATA wcs_label "Landsat" ows_title "Landsat" ows_srs "EPSG:4269 EPSG:4326" ows_extent "-82.3512420 -56.8510672 -33.9029540 13.0499433" wcs_resolution "0.00025602 0.00025602" wcs_formats "JPEG PNG24" wcs_nativeformat "ECW" END DUMP TRUE PROJECTION "init=epsg:4326" END END END Note that to use an ecw file (or jpeg2000 file) you just specify the name in the DATA line for the layer. The getcapabilities url for my service is: http://maps.gdal.org/cgi-bin/mapserv_landsat?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities I hope this helps.
