Dear all,
I have a problem with the app-schema plugin and the emission of
srsName-attributes for geometries.
In some cases the srsName is emitted in the URL form:
http://www.opengis.net/gml/srs/epsg.xml#4326
In other cases the URN-Notation is used: "urn:ogc:def:crs:EPSG::4326"
After some debugging I nailed this down to the superficial reason that in one
case the CRS has EAST-NORTH orientation (-->URL) while in the other case the
orientation is NORTH-EAST (--> URN).
But why? They all come from the same database and are declared equally.
After a lot more debugging I found that in the URN case a reprojections takes
place while the URL case does no reprojection at all.
Even more digging into the dirt showed me the following:
When a URN is emitted, the schema declares the geometry field as a direct child
(<targetAttribute>ef:geometry</targetAttribute>) of the target element
(<targetElement>aqd:AQD_SamplingPoint</targetElement>).
When a URL is emitted, the schema declares the geometry as a second level child
(<targetAttribute>sams:shape/gml:Point</targetAttribute>) of the target
(<targetElement>aqd:AQD_Sample</targetElement>).
The even deeper reason seems to be that the routine
org.geotools.feature.type.FeatureTypeImpl.getCoordinateReferenceSystem does not
recursively searches into complex types to find a geometry.
Any ideas how to force URN notation?
BTW, I use geoserver 2.7.0 with all "officially" bundled libraries.
