#2659 closed defect (fixed)

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

Reported by: billinb Owned by: warmerdam
Priority: normal Milestone: 1.5.4
Component: OGR_SRS Version: svn-trunk
Severity: normal Keywords: epsg


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?

This belongs to PROJ.4 and should rather be reported there :

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

Resolution: fixed
Status: reopenedclosed

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.
