Re: [mapserver-users] mapserver OGR does not forward BBOX at all

Thu, 31 Mar 2022 23:30:46 -0700

Hi,

Thanks for the hint. That server seems to support WFS 1.0.0 but I did not want to rely on such an old standard as I don't know how long they will keep this up. I am seeing a lot of providers around here that drop 1.0.0 support. If OGR does not work I guess I'll have to try anyhow.

Hi,

 

Have you tried the connectiontype=WFS alternative https://mapserver.gis.umn.edu/ogc/wfs_client.html? I am not sure what WFS versions it supports.

Aihe: Re: [mapserver-users] mapserver OGR does not forward BBOX at all

 

I looked a little deeper and this is the output of the error log (our docker did not distinguish between error and access log putting everything into the terminal).

I hope, someone will notice what is going on? I think it is strange that there are calls to "describeFeature" but no "getFeatrue" at first. And once the "getFeature" is there it is lacking the BBOX.

Thank you guys very much for your effort!!

Hi,
thank you for the fast reply. Unfortunately, even with the srs given with the bbox the "Fetch" command does not forward any bbox at all. So mapserver / OGR fetches up to the max number of features given no matter where they are located. They are then filtered out by mapserver using the original bbox because they do not fit (just the first 500 or so).

Hi Lars,

Might this help?

geoserver - WFS and WMS query SRS parameter and BBOX usage - Geographic Information Systems Stack Exchange <https://gis.stackexchange.com/questions/225535/wfs-and-wms-query-srs-parameter-and-bbox-usage>

I haven’t done much with the WFS tech but based on the link above, you may need to provide the crs info for the bbox.

In their example:

http://demo.geo-solutions.it/geoserver/tiger/ows?service=WFS&version=1.1.0&request=GetFeature&typeName=tiger:tiger_roads&srsName=EPSG:3857&bbox=40.7,-74,40.8,-73,urn:ogc:def:crs:EPSG:4326&maxFeatures=1 <http://demo.geo-solutions.it/geoserver/tiger/ows?service=WFS&version=1.1.0&request=GetFeature&typeName=tiger:tiger_roads&srsName=EPSG:3857&bbox=40.7,-74,40.8,-73,urn:ogc:def:crs:EPSG:4326&maxFeatures=1>

Note the bbox is defined as:
bbox=40.7,-74,40.8,-73,urn:ogc:def:crs:EPSG:4326


If your bbox is the same as the requested projection:
your bbox in the wfs request would be:

BBOX=545592,5806696,548144,5810131,urn:ogc:def:crs: EPSG:25832

Or the epsg code at the end would be whatever units your bbox is in.
Note, the bbox EPSG code can be different than the srsName

Hi All,

First of all, thank you for your support and great work on Mapserver!

I have a strange issue using either OGR WFS driver on Mapserver 7.6.4-1 or ogrinfo (GDAL 3.0.4, released 2020/01/28) on Ubuntu 20.

When I call on a particular public server, mapserver / gdal / ogr does not seem to forward the bbox. I had a similar issue before (over a year ago) on another server but this was fixed by an update in GDAL it seemed.

The Server is

`https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?`

The Layer is
`boris:BR_BodenrichtwertZonal`

A direct call from the browser works:

`https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetFeature&SRSNAME=EPSG:25832&BBOX=545592,5806696,548144,5810131&TYPENAMES=boris:BR_BodenrichtwertZonal <https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetFeature&SRSNAME=EPSG:25832&BBOX=545592,5806696,548144,5810131&TYPENAMES=boris:BR_BodenrichtwertZonal>`

I can see in Mapserver log (CONFIG "CPL_DEBUG" "ON"  CONFIG "PROJ_DEBUG" "ON") that the BBOX is missing:

`Fetch(https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?SERVICE=WFS&VERSION=1.1.0&MAXFEATURES=500&SRSNAME=EPSG:25832&TRUST_CAPABILITIES_BOUNDS=YES&REQUEST=GetFeature&TYPENAME=boris:BR_BodenrichtwertZonal <https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022?SERVICE=WFS&VERSION=1.1.0&MAXFEATURES=500&SRSNAME=EPSG:25832&TRUST_CAPABILITIES_BOUNDS=YES&REQUEST=GetFeature&TYPENAME=boris:BR_BodenrichtwertZonal>)`

By the way, it does not matter if WFS 1.1.0 or 2.0.0 are used.

Trying with ogrinfo:
```
ogrinfo -ro -spat 545592 5806696 548144 5810131 WFS:"https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022" <https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022> "boris:BR_BodenrichtwertZonal"

INFO: Open of `WFS:https://www.geobasisdaten.niedersachsen.de/doorman/noauth/WFS_boris_2022'
      using driver `WFS' successful.
Metadata:
  ABSTRACT=BORIS 2022 WFS by XtraServer

There should be some 62 Features in that bbox.

Any help is much appreciated.
