Hi Guillaume,
You seem to have discovered a Mapserver bug. It would
be very nice if you could take the trouble to report it
(so that it can be addressed / fixed).
http://trac.osgeo.org/mapserver/newticket
(everyone can create tickets, you just need to log in -
if you do not have an account, it is easy to create one)

Hi,
Wow! Adding a projection object on layer level fixed the problem. I was sure
the map level projection object was used when a layer was lacking it. Now the
result is the same than that of the WMS GeoTiff output (except for the
background color but that's not an issue).
Thanks a lot for your help!

Hi,
Mapfile looks good to me. I fear I have only two suggestions left:
- try adding projection also to the layer even it should use the map level
projection by default
- forget HDF5 for a moment and use some geotiff instead to check if there
are some oddities due to source data format

Hi,
Both mapfile and datasource are available in the first email I sent.
http://lists.osgeo.org/pipermail/mapserver-users/2011-November/070670.html
Filenames appear to be a little bit messed up but the data itself is
fine. I don't know why it went so wrong.
Mapfile :
http://lists.osgeo.org/pipermail/mapserver-users/attachments/20111104/78e5fa24/2011102811-0001.obj
Data (HDF5 format) :
http://lists.osgeo.org/pipermail/mapserver-users/attachments/20111104/78e5fa24/data-0001.obj
I intend to stick with 1.0.0 indeed. At least until it works... I will
look up 1.1.0's details in due time.

Pity that is was not just version mismatch. Could it be possible
to see your mapfile and info about the datasource?
Stay with version 1.0.0 while testing. With version 1.1.0 you must
give EPSG:4326 coordinates in Northing-Easting order which can make things more
complicated.

Hi,
I'm afraid it isn't. I didn't notice the request version I sent was a
"mixed" one but I tried Coverage on 1.0.0 and Identifier on 1.1.0 as well and
the result was basically the same.
Here is the 1.1.0 version of the error :
<?xml version="1.0" encoding="ISO-8859-1"?>

I of course spent a lot of time on the WCS server documentation
page. I saw no reference to such a problem, though. My request,
http://localhost/cgi-bin/mapserv.exe?
map=D:/Guillaume/ProjetCourantsGlaces/WCSproblem/2011102811.map&

is formatted the same way the example is :

Hi,
See examples in http://www.mapserver.org/ogc/wcs_server.html and try to avoid mixing
versions 1.0.0 and 1.1.0. Let's hope using "coverage" instead of "identifier"
will be enough.

Hi,
For some reason, the text part of the email didn't make it. It can
be read below.
Attachments can still be found in the first message :

Thanks.

Hi,
I installed MapServer 6.0.1 on Windows XP from MS4W. I cannot give you access
to my MapServer instance but I can show you what "-v" gives me :
MapServer version 6.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=KML SUPPORTS=PR
OJ SUPPORTS=AGG SUPPORTS=CAIRO SUPPORTS=FREETYPE SUPPORTS=ICONV
SUPPORTS=FRIBIDI
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT
SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI
SUPPORTS=THREADS SUPPO
RTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE
I am able to generate a GeoTiff file through the use of a WMS
service (see attachment : wmsoutput.tif). The request is :
http://localhost/cgi-bin/mapserv.exe?SERVICE=WMS&map=D:/Guillaume/ProjetCourantsGlaces/WCSproblem/2011102811.map&LAYERS=thelayer&VERSION=1.1.1&REQUEST=GetMap&bbox=-67.5,48.922499263758255,-64.6875,50.736455137010665&SRS=EPSG:4326&WIDTH=256&HEIGHT=256&FORMAT=GTiff
<http://localhost/cgi-bin/mapserv.exe?SERVICE=WMS&map=D:/Guillaume/ProjetCourantsGlaces/WCSproblem/2011102811.map&LAYERS=thelayer&VERSION=1.1.1&REQUEST=GetMap&bbox=-67.5,48.922499263758255,-64.6875,50.736455137010665&SRS=EPSG:4326&WIDTH=256&HEIGHT=256&FORMAT=GTiff>
However, I cannot do so with a WCS service. I first tried with :
http://localhost/cgi-bin/mapserv.exe?SERVICE=WCS&map=D:/Guillaume/ProjetCourantsGlaces/WCSproblem/2011102811.map&IDENTIFIER=thelayer&VERSION=1.0.0&REQUEST=GetCoverage&BBOX=-67.5,48.922499263758255,-64.6875,50.736455137010665&CRS=EPSG:4326&WIDTH=256&HEIGHT=256&FORMAT=GTiff
<http://localhost/cgi-bin/mapserv.exe?SERVICE=WCS&map=D:/Guillaume/ProjetCourantsGlaces/WCSproblem/2011102811.map&IDENTIFIER=thelayer&VERSION=1.0.0&REQUEST=GetCoverage&BBOX=-67.5,48.922499263758255,-64.6875,50.736455137010665&CRS=EPSG:4326&WIDTH=256&HEIGHT=256&FORMAT=GTiff>
, to which I can add :
&RESPONSE_CRS=EPSG:4326
for the same result (since 4326 is my native projection). Said
result is not a tiff file, but an error :
<?xml version='1.0' encoding="ISO-8859-1" ?>
<ServiceExceptionReport version="1.2.0"
xmlns="http://www.opengis.net/ogc";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.opengis.net/ogc
http://schemas.opengis.net/wcs/1.0.0/OGC-exception.xsd";>
<ServiceException code="NoApplicableCode"
locator="bbox">msWCSGetCoverage(): WCS server error. Requested BBOX
(-178.835708198757,2803.05273104522,179.552848002437,2906.98474680556) is outside requested coverage BBOX
(-70,45,-55,52)
</ServiceException>
</ServiceExceptionReport>
This error doesn't make sense to me. Which projection is it using
to get these silly values? Anyway, the BBOX in the request is definitely
included in the extent... Now what if I change the Response_CRS? I would expect
it to give me the same error, since it doesn't affect the requested BBOX. Yet,
this time no error is produced and I obtain a tiff file (see attachment :
wcsoutput.tif). The data is all wrong (0 everywhere), though. And if I open
both WMS and WCS obtained tiffs in QuantumGIS, they appear nowhere near each
other (for the same bbox... yes).
I attached the results of GetCapabilities and DescribeCoverage
requests as well as the MapServer logs (modified to map logs with requests).
The data source is an HDF5 file (see attachment : data.h5). I suspect an issue
on MapServer's side but I would be happy if you could tell me it's all my fault
(and how to fix it).
Oh, a last thing : it may or may not be related. I had issues with
the KML/KMZ WMS outputformats. Results for epsg:4326 and epsg:900913 were
completely different (and wrong, of course). I might open a new discussion on
this subject at some point.
Thank you all for your help.
Guillaume Loiselle
P.S. : If you want to test, know that epsg:900913 is the same as
epsg:3857 (which is more likely to be in your epsg reference file).
