Hello,
I'd be extremely grateful if someone could help me with a GeoServer
App-Schema issue that I've been battling to no avail!
I'm attempting to use the GeoServer App-Schema extension to map the
geometry and attribution stored in a data table of a PostGIS database to
a GMLAS.
My PostGIS data table 'depth_area' contains three columns: 'pk_id',
'depth_range' and 'geom'. I have registered the geometry column via the
AddGeometryColumn function and have confirmed that this column contains
valid geometry (polygons).
I have defined the app-schema mapping file and GMLAS as shown below. I
have checked that both are valid in an XML Editor.
On starting GeoServer, my workspace loads without errors. When GeoServer
is running, I make the following WFS request:
http://localhost:8080/geoserver/MyPrefix/ows?service=WFS&version=1.1.0&r
equest=GetFeature&typeName=MyPrefix:DepthArea&maxFeatures=2
This returns me a valid response (bottom of this email), and the
depth_range values are being successfully mapped across from the PostGIS
database. However, the geometry element is empty:
< MyPrefix:geometry/>
Can anyone suggest where I may be going wrong, looking at my
configuration below?
Best regards,
Ryan
