Hi,
First, the image coordinates x=9.5&y=50& do not hit Germany. Try with 475,98
and you will get something back but I am not sure if it is Germany either. To
get what you want you must also tell in the mapfile what attributes should be
included in the response with "wms_include_items"

Aihe: [mapserver-users] GetFeatureInfo returns no results. Why?
Hi there,
I am having problems getting a correct "GetFeatureInfo" from my WMS.
The URL looks fine, but I get this message:
"GetFeatureInfo results:
Search returned no results."
The WMS works well:
http://metafunctions.grid.unep.ch/cgi-bin/mapserv?map=/www/geodataportal/htdocs/mod_map/geo_wms_complete_last_year.map&;
service=wms&
version=1.1.1&
request=getmap&
format=image/png&
width=900&
height=450&
srs=EPSG:4326&
bbox=-180,-90,180,90&
layers=co2_gdp
The GetFeatureInfo looks like this:
http://metafunctions.grid.unep.ch/cgi-bin/mapserv?map=/www/geodataportal/htdocs/mod_map/geo_wms_complete_last_year.map&;
version=1.1.1&
request=getfeatureinfo&
width=900&
height=450&
srs=EPSG:4326&
bbox=-180,-90,180,90&
x=9.5&y=50&
query_layers=co2_gdp&
layers=co2_gdp
It should return the value for Germany. Here is the MAPserver code:
LAYER
NAME co2_gdp
METADATA
'wms_title' 'Emissions of CO2 per
GDP (PPP)'
'wms_timeextent' '2006'
'wms_extent' '-180 -90 180 90'
END # METADATA
PROJECTION
'init=epsg:4326'
END
STATUS OFF
CONNECTIONTYPE postgis
CONNECTION 'xxx'
TYPE POLYGON
DATA "the_geom FROM ****"
TEMPLATE 'dummy'
DUMP TRUE
CLASSITEM 'value'
......
Do I need to add something? Thanks for any adivce,
Stefan
