WMS and getFeatureInfo problem

[Bart van den Eijnden (OSGIS)]

Hi,

first of all, querylayers should be query_layers.

text/html is not supported by default, I believe you need to do some
templating for that. Check the following document and search for text/html:

http://mapserver.gis.umn.edu/docs/howto/wms_server

text/plain works using this request:
http://gridca.grid.unep.ch/cgi-bin/mapserv?map=/www/geodataportal/htdocs/mod_map/geo_wms.map&service=wms&version=1.1.1&request=getfeatureinfo&layers=gdp_capita,int_boundary_lines,continent_outlines&query_layers=gdp_capita&x=10&y=50&info_format=text/plain&bbox=-180,-90,180,90

Hope this helps.

Best regards,
Bart

> Hi there,gush, the last hours I spent with searching my way through pdfs,
email archives and how-tos... But somehow in vain....Why does my
getfeatureinfo not work? Probably just a tiny thing - as usual. But it's
getting somewhat frustrating.Thanks for any
hints!StefGetFeatureInfo:http://gridca.grid.unep.ch/cgi-bin/mapserv?map=/www/geodataportal/htdocs/mod_map/geo_wms.map&service=wms&version=1.1.1&request=getfeatureinfo&layers=gdp_capita,int_boundary_lines,continent_outlines&querylayers=gdp_capita&x=10&y=50&info_format=text/html&bbox=-180,-90,180,90
