Dear Stephen,
Martin Desruisseaux added the required projection class in october to the geotools trunk 2.4.
http://svn.geotools.org/geotools/trunk/gt/modules/library/referencing/src/main/java/org/geotools/referencing/operation/projection/LambertAzimuthalEqualArea.java
Hope that helps...
Cheers,
Beate

Betreff: [Geoserver-users] Epsg problem
All,
I accidentally posted this to GeoTools list instead of GeoServer....so for
any cross posting:
I'm running Geoserver 1.4, with postGIS datastore. I'm trying to create a
custom srs for a project, something I've successfully done a few times
before.....I unpack the gt2-epsg.jar, add the wkt to the epsg.properties
file, repack the jar. However this time I get a message saying "Could not
construct a SRS tranformation- No tranform for classification
'Lambert_Azimuthal_Equal_Area'". I looked at the existing srs's in the epsg
table, and at least a few use this tranformation...so I tried using one of
these srs's jut to test, and I get the same message. This implies (to me,
anyway) that some of the projections listed by geoserver actually don't
work. Is this true? Is there a list of the available tranformations for
Geoserver? Can I add a tranformation to Geoserver?
Lambert_Azimuthal_Equal_Area is listed in proj4, with code -proj laea.
Thanks Again,
Steve

This means it'll be available in Geoserver from 1.6.0 onwards, unless
the projection gets backported to geotools 2.3.x, which would make
it available in Geoserver 1.5.0 too. There is no chance the backport
can go back to gt2 2.2.3, the geotools version used by Geoserver 1.4.x series.
Let's see how hard is that. Martin, is the backport just a matter
of copying back a file and maybe an SPI, or something more involved?
It does not seem so easy given the original commit message (http://www.nabble.com/svn---r22295---in-geotools-trunk-gt%3A-module-referencing-src-META-INF-services-module-referencing-src-org-geotools-referencing-operation-projection-module-referencing-src-org-geotools-referencing-wkt-module-referencing-test-org-geotools-referencing-module--tf2477283.html#a6908672)
but I want to make sure...
Stephen, you could try out Geoserver 1.6.0alpha2, should be downloadable
here: http://docs.codehaus.org/display/GEOS/GeoServer+1.6-alpha2
and it has the projection you need already.
Cheers
Andrea

Forgive my ignorance but I'm certainly a user, not a developer. I'm using
gs 1.4.0. Would 1.4.1 have this class included? If so, I'll just go ahed
and upgrade, and that should do it. If it not included in 1.4.0, is there
any way for me to somehow add it?
Thanks,

Is there any list of the tranformations that are available to Geoserver 1.4?
I'm trying to choose a projection...I'd rather not go to 1.6 for a
production server...I want to see what I have available to me at the moment.
Thanks,

GeoServer 1.4.x series is based on geotools 2.2.x, which will not have the new reprojection. That is scheduled for a 2.4 release of Geotools. GeoServer 1.6.x is set to use GeoTools 2.4, so you will have to wait until it is released. If the reprojection fix does get backported to GeoTools 2.3, then it will be available in the official 1.5 release of GeoServer.
I hope that clears things up =)

Unfortunately no. The transformation API does not give us a restricted
set of working projections, but a flat list of all available ones
in the database 
It would be nice to have just a list of the supported ones, but I think
it would be very expensive on a computational point of view.
Just loading all the authorities takes some 6 seconds, testing projections would require a lot more...
Anyways, the following list of classes should give you an idea of the
supported projection types:
http://svn.geotools.org/geotools/branches/2.3.x/module/referencing/src/org/geotools/referencing/operation/projection/
Wheter a single EPSG code works or not does not depend solely on
the projection afaik. You have to try to make sure.
Cheers
Andrea
