But I don't know about the residual difference between cs2cs and geotools,
nothing comes to mind right
(cs2cs).
Any more thoughts/suggestions?
Thanks,

Adding +towgs84=0,0,0 to cs2cs helps but the coordinates are a few

Hello Andrea-
I have attached an updated copy of the CylindricalEqualArea class
along with a test script. The CylindricalEqualArea class supports 2 alias
projections:
- World Behrmann (ESRI:54017)
- Lambert

Indeed quite off. This is happening because cs2cs is not applying any

Andrea-
Thanks for following up on this. So it sounds like the class I wrote
is ok but the test scripts need to be tweaked. Do you still want me to do a
pull request or can you commit the code on my behalf. I
