Add EPSG 3410 PROJ.4 string to share/proj/epsg

Description
in the "share/proj/epsg" file in FWTools, for the entry for 3410, it says: # NSIDC EASE-Grid Global # Unable to translate coordinate system EPSG:3410 into PROJ.4 format.
However we have been successfully using the PROJ.4 string +proj=cea +lat_0=0 +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m +no_defs
to work with this projection with gdal utilities. Can this projection definition be added to the file?
Thanks,
Brendan

The underlying problem is that importFromEPSG() does not support this coordinate system in GDAL/OGR. Reopening.

I have added support for translating transformation method 9834 (Cylindrical Equal Area) in trunk (r15751) and 1.5 branch (r15752). Now "testepsg EPSG:3410" produces valid results including this PROJ.4 formulation:
+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m +no_defs
This will be fixed in GDAL/OGR 1.6.0 and 1.5.4.
This belongs to PROJ.4 and should rather be reported there : http://trac.osgeo.org/proj/newticket
