Hi,
Layer 'gsml:GeologicUnit' fails the rendering process in WMS because it
doesn't have any defined geometry, maybe the rendering pipeline should
be more explicit about this.
Anyway, if you are interested in WMS I guess is because you want to
actually draw something so a geometry is required :)
Layer 'gsml:MappedFeature' defines the shape geometry property in is
mappings:
<AttributeMapping>
<targetAttribute>gsml:shape</targetAttribute>
<sourceExpression>
<OCQL>SHAPE</OCQL>
</sourceExpression>
</AttributeMapping>
If you check the associated schema:
http://www.geosciml.org/geosciml/2.0/xsd/geologicFeature.xsd
you can see that the shape property has type 'gml:GeometryPropertyType'
which mark this property as a geometry property:
<element name="shape" type="gml:GeometryPropertyType">
<annotation>
<documentation>
Points to the GML shape object that describes
the geometry of the MappedFeature. The shape
object may have any dimensionality. The shape
of a mapped feature is determined by observation,
not assertion
</documentation>
</annotation>
</element>
So if I understood the problem correctly, you basically need to define a
geometry property in you schema and define the correct mapping.
Regards,
Nuno Oliveira
