[OpenLayers-Dev] Buffer/radius in GetFeatureInfo request

[Andreas Hocevar]

Hi,

If it is possible for you to upgrade to GeoServer 1.7.6, you will get
intelligent point radius selection for free, without the need to provide
an extra vendorParam. The way it works is that it analyzes the SLD that
created the symbol, and will return all the features that are *visible
on the map* at the spot that you clicked.

Regards,
Andreas.
