[Geoserver-users] 1.6.5 + PostGIS: Getting gml:_ImplicitGeometry from GetFeature requests

Dustin_Parker · October 8, 2008, 5:52pm

Using 1.6.5 and asking for features that have WKT starting with

SRID=4326;GEOMETRYCOLLECTION(POLYGON(( …

I get this in the GetFeature response:

…
<gml:_ImplicitGeometry srsName=“urn:x-ogc:def:crs:EPSG:6.11.2:4326”/>
…

(Without any actual geometry.)
The same datastore accessed through the community-schemas datastore gives back an empty gml:_Geometry element. What’s going on?

I have no idea... the community schema setup replaces many core
GeoServer modules including the WFS one... I'm not at all familiar
with the community schema one so, I hope Ben has an answer for
you. To the best of my knowledge, the standard WFS module never
generates a gml:_ImplicitGeometry in the output.

Cheers

But that first XML fragment is from the standard WFS module (built from SVN's 1.6.5 tag). Only the second one is from the community-schemas module (and it is probably symptomatic of the problem with the regular datastore).

Ah, I see. Any chance you can provide us with a data sample plus
request so that we can reproduce the issue?
Cheers

(Sorry, I didn’t mean to send that last reply directly to you.)

Okay; I’ve attached a SQL table creation script for PostgreSQL and the feature type’s info.xml. Here’s the request:

[endpoint reference]?service=WFS&request=GetFeature&typename=fsi:testGeomCollection

And the result, like before:

<gml:_ImplicitGeometry srsName=“urn:x-ogc:def:crs:EPSG:6.11.2:4326”/>

I can also debug and code if you can point me towards the appropriate classes.

testGeomCollection.sql.bz2 (971 Bytes)

testGeomCollection_info.xml.bz2 (465 Bytes)

Hi Dustin,

Thanks for providing some data. I tries this out and it is indeed a bug with the gml3/wfs 1.1 encoder. Filing a jira issue here:

http://jira.codehaus.org/browse/GEOS-2276

Note: The gml2/wfs 1.0 encoder handles this ok.
