Hi all,
I’m not sure if this is a bug or a feature so I thought I’d ask here, though I suspect a feature.
I’m trying to select stuff from a datastore using WFS, getfeature and outputFormat. I’m using bbox to provide the co-ordinates of the area I want things to be selected from, i.e.:
http://localhost:8080/geoserver/wfs?request=getfeature&service=wfs&version=1.0.0&typename=j2:woodland_geometry&outputFormat=GML2&bbox=-5.93395132390662,50.9761679303823,-1.3995414878861223,53.776153474504284
The quirk is, when the version is 1.0.0 as shown above, it works fine and returns results. But when I change the version number to 1.1.0, I get zero results. Is bbox not allowed to work in the 1.1 spec? If not, how am I supposed to get data, using CQL? It doesn’t seem to make a difference what the outputFormat is set to (GML2 or 3).
Disclaimer: I’m fine with leaving it on version 1.0.0, I’m just trying to figure out what’s going on.

Hi,
If it is a bug then the bug is in the WFS 1.1 specifications which flipped the coordinate axis order. If you turn around the bbox coordinates from lat/lon to lon/lat in your 1.1.0 request then you should get some features back again.

Sorry, I meant from lon/lat to lat/lon, naturally.

Thanks Jukka - that seemed to do it. I had noticed the co-ords in quite a few geoserver things were flipped around in strange kinds of ways, at least now I know at least part of the blame goes to the OGC.

Actually it's the opposite: WFS 1.0 -> lon/lat
WFS 1.1 -> lat/lon
