Arnaud,
which SRS's are you advertizing in the MAP file? You need to advertize
them using WMS_SRS (or the more general OWS_SRS) metadata.
Can you post your current MAP file?
Best regards,
Bart

Hello,
When I issue a GetCapabilities on my installation of mapserver, using
the following URL:
http://localhost/cgi-bin/mapserv?map=/var/www/workshop/ita
sca.map&service=WMS&version=1.3&request=GetCapabilities
I get a capabilities document showing:
<WMT_MS_Capabilities version="1.1.1">
So, the service expects requests of version 1.1.1 of the WMS spec, but
when I issue a GetFeatureInfo with this URL:
http://localhost/cgi-bin/mapserv?map=/var/www/workshop/itasca.map&SRS=EPSG:4326&BBOX=-99.30245,43.4354,-87.36445,49.404399999999995&TRANSPARENT=TRUE&BGCOLOR=0xFFFFFF&EXCEPTIONS=application/vnd.ogc.se_xml&WIDTH=800&HEIGHT=400&LAYERS=airports&STYLES=&REQUEST=GetFeatureInfo&VERSION=1.3&SERVICE=WMS&INFO_FORMAT=gml&X=363&Y=121&FEATURE_COUNT=100&QUERY_LAYERS=airports
I get the following error:
<ServiceExceptionReport version="1.1.1">
<ServiceException code="InvalidSRS">
msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS
must be valid for all requested layers.
</ServiceException>
</ServiceExceptionReport>
hmm. But then, if I change the SRS parameter name to CRS, I get a
valid (though empty) result:
<msGMLOutput
xmlns:gml="http://www.opengis.net/gml";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
</msGMLOutput>
The weird thing is that in the version 1.1.1 of the spec, there is no
CRS parameter for the GetFeatureInfo, but an SRS parameter. SRS was
changed to CRS at version 1.3.
It looks to me like a bug, am I wrong?
Best regards,
Arnaud
Last Minute Addendum: When I try with the equivalent (projected)
native logical bbox, in the native SRS (EPSG:26915, this is the Itasca
demo!) mapserver doesn't mind the name of the SRS param. Both SRS and
CRS work. Now, I'm totally lost o_O
Will mapserver refuse to work properly if asked for features with a
4326 box?
Thanks for any information!
