Hi,
I have never known that the srs demo, for example
http://localhost:8080/geoserver/web/wicket/bookmarkable/org.geoserver.web.demo.SRSDescriptionPage?3&code=EPSG:2393
show an internal description. I have been comparing that info against WKT from
the EPSG registry
http://epsg-registry.org/export.htm?wkt=urn:ogc:def:crs:EPSG::2393 and thought
that Geoserver is definitely having wrong descriptions but been happy that
Geoserver still, probably due to some clever trick, works right also as WMS
1.3.0 and WFS >=1.1.0.
I appreciate this improvement. It should make it much easier to handle cases
like
https://osgeo-org.atlassian.net/browse/GEOS-8206 in the future.

Aihe: [Geoserver-devel] Improving the SRS demo page to show possible axis
orders (EPSG and internal)
Hi,
as you probably know the "axis order issue" keeps on being source of issues.
One of the problems is that people keep on assuming GeoServer picks in their
opinion the
wrong axis order, and the demo page is not helping because it only shows the
internal
axis order, the one forced east/north, instead of showing the external one
chosen
by the latest OGC protocols.
I've prepared a pull request changing the SRS description page to hopefully
show both cases,
in two separate tabs, here is an example for a projected SRS that in the EPSG
database is oriented
North/East (kept the text small, but if you are interested focus on the two
axis declarations
at the end, and the latitude/longitude bits in the middle):
[Inline image 1]
[Inline image 4]
The code is "flipping" the axis of the code using exactly the same logic as WMS
1.3 (calling
the very same method), see the pull request for details:
https://github.com/geoserver/geoserver/pull/2557
Hopefully this will help some in figuring out eventual axis order issues.
As an improvement it's probably not something that we want to backport after
the RC... and honestly
I did in it my spare time, I'm not pressed to ask for a backport to start with
:-p
Comments, proposed code improvements, all welcomed.
Cheers
Andrea
