Re: [mapserver-users] WFS Client returns data at random with very same call

Title: SkenData Email Signatur

So here is the working not working setup. Unfortunately the working OGR WFS client layers are all private so I can not share them.

This call delivers objects as expected:
http://localhost:8181/cgi-bin/mapserv?map=/var/www/html/wfs.map&SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&Maxfeatures=10&TYPENAME=TestLayer
This one, too:
http://localhost:8181/cgi-bin/mapserv?map=/var/www/html/wfs.map&SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&Maxfeatures=10&TYPENAME=TestLayer

Data is delivered in the correct srs (verified manually with QGIS).

This call doesn't work as described before as BBOX is not transmitted to external server:
http://localhost:8181/cgi-bin/mapserv?map=/var/www/html/wfs.map&SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&BBOX=791880.72463009,6321925.37255709,792929.63787777,6322786.10157277&TYPENAME=TestLayer

While the same direct call works:
http://sg.geodatenzentrum.de/wfs_info?SRSNAME=EPSG:3857&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&BBOX=791880.72463009,6321925.37255709,792929.63787777,6322786.10157277&TYPENAME=info:dop
(funny, epsg 3857 is not in the capabilities but works anyhow)

I hope you can find out what is going wrong. Thanks so much for looking into this!

Best

Hi,

 

Have you already tried to use WFS connection instead of OGR connection?

Aihe: Re: [mapserver-users] WFS Client returns data at random with very same call

 

Dear all,
I apologize for finding and posting bits and pieces not all at one time.
I fired up 'CONFIG "CPL_DEBUG" "ON"' and there I see, that
"""

HTTP: Fetch(http://url-to-external-server?SERVICE=WFS&VERSION=1.1.0&MAXFEATURES=1000&REQUEST=GetFeature&TYPENAME=dop)
"""
So there is no BBOX. On other layers I see
"""
GDALOpen(/vsicurl_streaming/https:...
"""
with BBOX.
No wonder I do not get reliable results if the server is calling some 1000 whatsoever result objects and starts filtering the bbox after.

Any idea what is happening? Or is this something for a GDAL thread?

Best
Lars
