@ghobona I see - we took that from the WMS spec, maybe there was an update. Who could provide us with the content? Then we can add it on short notice, no problem.
@RogerLott Could the CRS DWG please review the CRS84 definition and confirm whether or not an <ellipsoidalCS>
element is missing?
Hi Gobe,
Yes it is missing from the GML which gives:
It should be:
@RogerLott Thanks for the review. I'll prepare a draft revision for the OGC-NA to consider and approve.
A proposed revision is at https://github.com/opengeospatial/NamingAuthority/tree/crs84_ellipsoidalcs/incubation/crs84
The associated Pull Request is https://github.com/opengeospatial/NamingAuthority/pull/207
As I was preparing the proposal, I discovered that the referenced EPSG.xsd file is no longer available. So it is not possible to validate the structure of the XML file by XSD. The EPSG.xsd file has the namespace urn:x-ogp:spec:schema-xsd:EPSG:0.11:dataset
. I presume it is a very old version of the schema, since the 2020 version has the namespace urn:x-ogp:spec:schema-xsd:EPSG:2.1:dataset
.
The topic will be discussed during the OGC-NA session on Monday 3rd October at 15:00 SGT.
The latest version of the EPSG XML schema is v2.2 . A download is available through https://epsg.org/gml-schema.html
EllipsoidalCS element is missing from CRS84 definition.
