[mapserver-users] Retrieve the getfeatureinfo by point coords

[Rahkonen Jukka (MML)]

Hi,


-          use fixed i=1&j=1

-          use fixed &width=2&height=2

-          push the clicked coordinates as first parameters of &BBOX=

-          calculate x+1, y+1 for completing the BBOX

I do not remember exactly if width and height can be 1 and BBOX just a point with MapServer, but 2x2 sized output and a real, small BBOX should works with all WMS servers.

Aihe: [mapserver-users] Retrieve the getfeatureinfo by point coords

Hi,
I know the GetFeatureInfo is retrieving the information of all the features available in a clicked point using the map extend (bbox) and the pixels references I,J
I'm searching some workaround in mapserver to retrieve the same information of a GetFeatureInfo using the x,y coords.

My need is to avoid to use the BBOX and the pixel I,J.

I guess this is not available in wms specs. But with some custom parameter should it be possible.
?

thx.
