I have a data set which contains global points. I would like to convert from long/lat to Albers equal area. However, the http://spatialreference.org proj4 world parameter values are actually for the USA.

Albers equal area might not be the best, both that is what I need to do.

@whuber: The wikipedia article shows a map of the world. Perhaps he wants just that? –  AndreJ May 31 '13 at 9:44
@Andre I think you're right; I'll withdraw my comment. Thanks. For the record, the Wikipedia article on the Albers projection contains an illustration of a world map (and in the caption provides the necessary parameters, although these are not the only ones possible). –  whuber May 31 '13 at 9:45
That's exactly it...thanks so much! –  user1544953 May 31 '13 at 11:21
