Hi all,=20
I'm would like to retrieve all objects of a specific layer (station_fr) =
which are in my current map extent. So I'm supposed to use =
mode=3Dnquery, specified an imgext ... and I was thinking that all =
parameters required were here.=20
But I always get all the objects of my layer even if I have only one in =
my current view.

Which parameters are mandatory for a nquery in an area of interest =
selection ?

here is the URL ...
