Hi Carl, I'm sorry, I have to rise to the bait on this one. It's been bugging me. > <gml:Point gml:id="point96" srsName="http://www.opengis.org/CRScatalogue.xml#epsg_4326"> > <gml:pos>33.001111 96.68142</gml:pos> > </gml:Point> Can someone please standardize: urn:ogc:def:crs:EPSG:6.6:4326 http://www.opengis.org/CRScatalogue.xml#epsg_4326 urn:ogc:def:crs:EPSG:4326:6.6 urn:EPSG:geographicCRS:4326 epsg:4326 http://www.opengis.net/gml/srs/epsg.xml#4326 www.epsg.org#4326 urn:epsg:v6.6:coordinateReferenceSystem:4326 urn:ogc:def:crs:OGC:1.3:CRS84 All of these have been taken from standards body publications. It would be nice to only have to deal with one, maybe two URNs; 4326 for 2D, 4979 for 3D. PIDF-LO profile recommends the first, since that is published in OGC 05-010; but now I see yet another. Carl, are we right in using "urn:ogc:def:crs:EPSG:6.6:4326"? Can we expect to see more forms in the future? In other words, is there a need to do more than specify a common form and define a pattern, or means of parsing the URN? Cheers, Martin p.s. > <gml:location> Incidentally, I thought that the location element was deprecated.
