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.
In the (attached) map file -a barely modified itasca.map from the demo-
I advertise epsg 26915, but I thought (erroneously) that the epsg 4326
would be supported as well.
Still, I found it funny that both CRS and SRS work for valid Epsg IDs,
and that SRS doesn't work for invalid Epsg IDs.
Regards,
Arnaud
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!
