[Mapserver-users] GetFeatureInfo from selected rectangle???

[Howard Mark]

In the mapfile, set the 

toleranceunits =  pixels 
tolerance = 1000 

This will handle the extend of just about any display.
The WMS call should specify the bbox, X,Y and radius.
I'd make sure the radius (in pixels) is set high enough to cover the bbox
extent, although this does not seem to have an effect on the final result.
Make sure &FEATUREDOUNT=[Maximum Expected Features]

Hope this helps,

Mark
