Hi Francois,
=20
I am not sure if this will address your problem, but I think you have to
replace imgext to mapext. By doing this and playing with the bounding
box coordinates (especially, the -35.000 one), I have been able to
display only a part of the records.

Bye,
Paul

Subject: [Mapserver-users] Get all objects of one layer in map extent
using nquery

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.
=20
Which parameters are mandatory for a nquery in an area of interest
selection ?
