Hi Maciej,
the specification of a user-defined CRS is explained in
http://docs.geoserver.org/stable/en/user/advanced/crshandling/customcrs.html.
We specified a new CRS for the COSMO NWP model (http://www.cosmo-model.org/ )
as follows:
PROJCS["COSMO projection",
GEOGCS["COSMO Coordinate System",
DATUM["COSMO Kugel", SPHEROID["Erdkugel", 6371229.0, 0.0]],
PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
UNIT["degree", 0.017453292519943295],
AXIS["Longitude", EAST],
AXIS["Latitude", NORTH]],
PROJECTION["Rotated_Latitude_Longitude"],
PARAMETER["central_meridian", -170.0],
PARAMETER["latitude_of_origin", 40.0],
PARAMETER["scale_factor", 1.0],
PARAMETER["false_easting", 0.0],
PARAMETER["false_northing", 0.0],
UNIT["m", 1.0],
AUTHORITY["EPSG","1000003"]]
The COSMO model uses a "rotated latitude longitude" projection. This projection
is not supported by GeoServer. If you wish then I can provide you the Java
class that has to be added to the gt-referencing.jar library.
Kind regards,
Jürgen

Betreff: [Geoserver-users] Rotated pole coordinate system
Hi,
is it possible to define in geoserver a custom coordinate system to handle
rotated pole coordinates, quite common in NWP world?
Here is WKT working with gdal_translate. Last line is the key one, of course.
PROJCS["unnamed",
GEOGCS["WGS 84",
DATUM["WGS_1984",
SPHEROID["WGS 84",6378137,298.257223563,
AUTHORITY["EPSG","7030"]],
TOWGS84[0,0,0,0,0,0,0],
AUTHORITY["EPSG","6326"]],
PRIMEM["Greenwich",0,
AUTHORITY["EPSG","8901"]],
UNIT["degree",0.0174532925199433,
AUTHORITY["EPSG","9108"]],
AUTHORITY["EPSG","4326"]],
PROJECTION["custom_proj4"],
EXTENSION["PROJ4","+proj=ob_tran +o_proj=longlat
+to_meter=0.0174533 +lon_0=-180 +o_lat_p=37.5 +o_lon_p=199.3
+ellps=WGS84 +datum=WGS84 +wktext +no_defs"]]
Regards
Maciej
