[Geotools-devel] [jira] (GEOT-4563) SrsSyntax ignored when encoding EngineeringCRS

Tue, 10 Sep 2013 02:23:28 -0700

Issue Type: Bug Bug
Affects Versions: 11-beta
Assignee: Justin Deoliveira
Components: referencing, xsd-gml
Created: 10/Sep/13 4:21 AM
Description:

I have a 3D EngineeringCRS defined in GeoServer epsg.properties as:
700001=LOCAL_CS["Mine coordinates",LOCAL_DATUM["Unknown",0],UNIT["m",1.0],AXIS["x",OTHER],AXIS["y",OTHER],AXIS["z",UP]]

(1) According to gt-referencing CRS.getAxisOrder, any CoordinateReferenceSystem that is not instanceof ProjectedCRS or instanceof GeographicCRS has AxisOrder.INAPPLICABLE.

(2) According to gt-xsd-gml2 GML2EncodingUtils.toURI, any CoordinateReferenceSystem with AxisOrder.INAPPLICABLE whall be encoded with SrsSyntax.OGC_HTTP_URL, regardless of the supplied option. There is a TODO questioning this behaviour.

(1)+(2) results in GeoServer SrsSyntax.OGC_HTTP_URL responses srsName="http://www.opengis.net/gml/srs/epsg.xml#700001" even when another syntax such as SrsSyntax.OGC_URN or SrsSyntax.OGC_HTTP_URI is selected for WFS. This prevents GeoServer from providing WFS 1.1.0 or WFS 2.0.0 compliant service for this CRS.

The fix is to remove AxisOrder.INAPPLICABLE from the test in gt-xsd-gml2 GML2EncodingUtils.toURI. This is a backwards-incompatible change.
