[GRASS-user] lat long to Behrmann equal area cylindrical projection

[Ilona Naujokaitis-Lewis]

Hi,
I am working trying to transform my lat/long datum d_wgs_1984 to the
Behrmann cylindrical equal area projection. I have read conflicting
information on whether this is a format supported by PROJ.4, but when I have
tried some functions in GRASS they have all failed ending in the following
error: No translation for Behrmann to PROJ.4 format is known.
I have been using the g.proj command and have tried using WKT, PROJ.4, *.prj
files, and importing a georeferenced TIF with the Behrman projection (set in
arcGIS) but I always receive this error. I am listing here the wkt that I
had been using

This is what the wkt looks like (I accessed this through
http://www.spatialreference.org/ref/esri/54017/)
I did try to use this ESGS # 54017, but this resulted in an error:#ERROR 6:
EPSG PCS/GCS code 54017 not found in EPSG support files.  Is this a valid
EPSG coordinate system?

PROJCS["World_Behrmann",
    GEOGCS["GCS_WGS_1984",
        DATUM["WGS_1984",
            SPHEROID["WGS_1984",6378137,298.257223563]],
        PRIMEM["Greenwich",0],

        UNIT["Degree",0.017453292519943295]],
    PROJECTION["Behrmann"],
    PARAMETER["False_Easting",0],
    PARAMETER["False_Northing",0],
    PARAMETER["Central_Meridian",0],

    UNIT["Meter",1],
    AUTHORITY["EPSG","54017"]]


Any further ideas on how to reproject my data (which is the entire western
hemisphere, ie. northern and southern hemisphere) into this equal area
projection
would be great.

Thanks hugely in advance,
Ilona
