[Geoserver-users] Get WFS on a group layer

Hi,

Can anyone help me understand if I can make a WFS getFeatures request to a group layer?

Thank you,

Hi Tiago,
layer groups are incompatible with the WFS protocol.
Each “feature type” reported in the capabilities must have a single GML schema, but layers in a group typically have different schemas.
As a result, the GeoServer WFS implementation does not advertise layer groups, nor offers a way to call them directly.

That said, one can ask for multiple feature types in a single GetFeature request, by enumerating the desired target types, e.g:

https://gs-main.geosolutionsgroup.com/geoserver/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=ogcapi%3Atasmania_roads,cite:tasmania_water_bodies

As you can see, the result is probably confusing, as all features are lumped into a single collection, it’s up to the client
to be ready to parse this mixup (the same happens when requisition GeoJSON, buf if one was to ask for shapefile,
then they would get a zip file with two separate shapefiles instead)

Cheers
Andrea

Thank you for your reply.

The main problem is that we’ve a lot of layers in a group layer, and all our map exporters are implemented by calling WFS POST getFeatures.
We need to review our implementation in order to call WMS instead.

Cheers,
