[Geoserver-users] Additional WMS GetFeatureInfo questions

While we're at it, I have two additional question for the list
regarding GetFeatureInfo requests:

* Is there a way, other than recompiling the servlet, to adjust the
html layout of the output? Some configuration file perhaps?

* Is there a way to support info on multiple features at the same XY?
My initial experience says that only one feature is returned when
there may be many features at the query point.

Thanks,

QUESTION 1:
how is your X and Y parameter set/pixel coordinate system implemented?
0,0 in the upper left corner?

QUESTION 2:
where can i configure the "snapping" for focussing getFeatureInfo in
server administration?
i.e. adjust the snapping tolerance in pixel?

QUESTION 3:
why does parameter I and J according to OGC WMS Specs
(http://portal.opengeospatial.org/files/?artifact_id=14416)
return an error?

No. James had an idea for templates for html output, but never got anywhere near implementation.

My suggestion is use GetFeature from WFS and do an xsl transform on the GML in to the html you like. I consider GetFeatureInfo quite hacky - for one since it says nothing about the html style.

This is where you should _really_ use GetFeature. It's the operation you want. You can even set a range with a DWithin filter, so it'll get features within like X meters of the point clicked.
