[Geoserver-users] BBOX questions

Yin_Wentao_IS_Contr · September 24, 2015, 8:34pm

Some questions about BBOX filter:

In app-schema tutorial, MappedFeatrue is nested in GeologicUnit. If I want to use KVP bbox query, it will fail.

http://localhost:8081/geoserver/wfs?request=GetFeature&version=1.1.0&typeName=gsml:GeologicUnit&BBOX=120,-39,150,-33

But it works when using XML which specifies the path to the nested geometry.

Does this mean we have to include the geometry in the top level feature in order for KVP style bbox to work?

Thanks,
Wen

Wen,

I think that you are correct and that for KVP style bbox to work you may need to include the geometry in the top level feature.

The underlying conceptual problem is that, for complex features, nested geometries may belong to features only weakly related to the containing feature, such as the geometry of neighbouring features or the location of a remote observer. There is no general rule for when a nested geometry might be appropriate for a kvp bbox request.

Kind regards,
Ben.

Ben,

Thanks for the clarification.

Best regards,
Wen

Ben,

One more geometry related question:
In order to show complex feature layers on WMS, is it true that geometry element must be the direct child of the root element of the top lever feature?
Like the 'shape ' in MappedFeature?

<gsml:MappedFeature gml:id="mf.25699">
<gml:name>Some basalt</gml:name>
...
<gsml:shape>
...
</gsml:shape>
</gsml:MappedFeature>

Is it possible to make it work if the geometry is in nested feature?

Any advice on using Geoserver with AIXM5.1 for WFS/WMS?

Thanks,
Wen

Wen,

I have not tried using WMS with a type that does not have a geometry as a direct child. As you guessed, I do not think it will work, for the same reason as for BBOX.

I have seen some mention of AIXM but have not used it. Please start a new thread to draw attention.

Kind regards,
Ben.
