But instead of using the obvious north and south poles at the top and bottom (where there's maximum distortion), it uses an axis that goes (...) (22 years ago, 3-Jun-02, to lugnet.off-topic.geek)

It's a transverse projection, probably at 45º of rotation--it looks like a Lambert, but without access to my Bugayevsky and Snyder [1] I couldn't tell you what the exact variation is called.

| | | | | | (...) I agree with your assessment that it is a transverse project, but I thought Lambert was only suitable for projections of a hemisphere? I could be mistaken though, it's been several years since I worried about projections and never did much (...) (22 years ago, 5-Jun-02, to lugnet.off-topic.geek)
