Hi list,
I'm setting up a WMS server able to handle getFeatureInfo requests. It's
fine using this kind of parameters :
?map=/data/atlas/MD_77/MD_77.map&layers=MD_77&SRS=EPSG%3A27572&FORMAT=agg&SERVICE=WMS&VERSION=1.1.1&&REQUEST=GetFeatureInfo&STYLES=&EXCEPTIONS=application/vnd.ogc.se_xml&BBOX=676399.0098411,2370419.2078563003,948746.3365309,2519140.3959517004&X=500&Y=250&INFO_FORMAT=text/plain&QUERY_LAYERS=MD_77&WIDTH=1031&HEIGHT=563
but on the MapServer WMS Howto, I've seen a working example I didn't
manage to use on my own server :
http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?&SERVICE=wms&VERSION=1.1.1&REQUEST=getfeatureinfo&LAYERS=popplace&QUERY_LAYERS=popplace&x=305&y=200
This second url doesn't use BBOX, SRS, HEIGHT, WIDTH parameters. When I
try to do that, mapserv complains about the lack.
So, how does that one work ? How does mapserv compute geo x,y without
BBOX nor h,w (as 305,200 does look as screen coordinates !) ? Is it a
kind of DMSolutions magic, something embedded into the mswms_gmap
wrapper which populates the missing params ?
Thanks,
