[Geoserver-devel] Does Geoserver supports EPSG:4900(LGD2006)?

Hi All,
   My source layers need to projected with EPSG:4900 (LGD2006).
   Geoserver could not identify this projection if provided in SRS box.

   So, I got the OGCWKT from
http://spatialreference.org/ref/epsg/4900/ogcwkt/
   and included the new definition in epsg.properties file as:

    4900=PROJCS["LGD2006",GEOGCS["LGD2006",DATUM["Libyan Geodetic Datum
2006",SPHEROID["International
1924",6378388.0,297.0,AUTHORITY["EPSG","7022"]],TOWGS84[-208.4058,-109.8777,-2.5764,0.0,0.0,0.0,0.0],AUTHORITY["EPSG","6754"]],PRIMEM["Greenwich",0.0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.017453292519943295],AXIS["Geodetic
latitude",NORTH],AXIS["Geodetic longitude",EAST],AXIS["Ellipsoidal
height",UP],AUTHORITY["EPSG","4900"]]]

   So, while defining the featuretype for the same, if i provide SRS=4900
and click "generate", I get the following exception:

The following exception was thrown:

    * class org.opengis.geometry.MismatchedDimensionException: Illegal
transform of type "ConcatenatedTransform".

I may be wrong in defining the projection for EPSG:4900 in the
epsg.properties file
OR
Geoserver does not support LGD2006 Projection.

Any suggestion on this will be helpful.

Suvajit

Hi All,

Hi Suvajit,
first off, a couple of directions about making questions on
the mailing lists:
- you have to subscribe to a mailing list before posting a
   question
- the devel list is for meant for developers to discuss the
   technical details and direction of GeoServer, not for users
   making questions about GeoServer features or issues

Ah, I see. EPSG:4900 is a 3D spatial reference system, GeoServer
can only handle 2D data at the moment. So no, EPSG:4900 is not
supported.
