[OpenLayers-Users] Zoom to filtered feature

[Michał Średnicki]

Thank you Ravi. The parcel layer is served also via WFS but I don't have
much experience with dealing with WFS layers in OpenLayers. Can you say
something more about this method of receiving feature bounds in Open Layers?

Regards,

Michal
