[mapserver-users] RE Problem using WMS GetFeatureInfo in OpenLayers with different projections

[Steve.Toutant at inspq.qc.ca]

Anything in mapserver logs?
add debug 5 in the layer definition AND in your MAP definition

In the metadata tag of your layer try set 
"wms_srs"   "EPSG:4326 EPSG:900913"

[mapserver-users] Problem using WMS GetFeatureInfo in OpenLayers with 
different projections










Hi,

I am trying to send WMS GetFeatureInfo request using OL WMSGetFeatureInfo 
control. My source data is in 4326 and map is displayed in 900913. I have 
something like this in mapfile:

LAYER
 NAME "mylayer"
 TYPE RASTER
 STATUS ON
 PROJECTION
   "init=epsg:4326"
 END 
 METADATA
   "wms_srs"   "EPSG:4326"
   "wms_title"  "whatever"
   "gml_include_items" "value_0"
   "gml_value_0_alias" "Value 0"
   "gml_geometries" "none"
 END
 OPACITY 0
 TILEINDEX "mylayer_index"
 TILEITEM "LOCATION"
 TEMPLATE void
 DUMP true
END

In OL, I am using something like:

           var layer = new OpenLayers.Layer.WMS(
               'mylayer',
               'http://my.domain.com/cgi-bin/mywms?',
               {
                   format:'image/png',
                   transparent:true,
                   isBaseLayer:false,
                   layers:'mylayer'
               });

           control = new OpenLayers.Control.WMSGetFeatureInfo({
               url:  "http://my.domain.com/cgi-bin/mywms?",
               layers: [layer],
               hover: false,
               infoFormat: 'gml',
               maxFeatures: 1
           });

wms_srs in WEB part is "EPSG:900913 EPSG:4326" so it can serve data in 
both projections

The problem is - when I click to get the info I get "Internal server 
error" and in apache log I get "Segmentation fault" followed by "Premature 
end of script headers: mywms"

For test, I reprojected my source rasters to 900913, changed PROJECTION 
and wms_srs in LAYER to 900913 and then everything works.

Does anyone know what can be the problem? I am using MapServer 6.0.1 on 
debian os.

Thanks for any help

regards, dejan
