Found this while looking for new LUG map graphics last night.. (URL) never seen a projection like this before. Anyone know about them? This one's from the CIA. Uh oh, it's happening again... [mesmerized] can't.. stop.. staring at it.. must.. print (...) (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. There are so many names for so many slight (...) (22 years ago, 3-Jun-02, to lugnet.off-topic.geek)

(...) It's like one of those area conserving projections, the kind that stretch antarctica across the bottom. 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)

(...) 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)

(...) For hemispheric mapping, conic projections were generally used. Lambert can be applied cylindrically, though: (URL) Which gives the map severe t/b end compression. I'm not sure, again, what the maths are that govern the original map Suz put (...) (22 years ago, 5-Jun-02, to lugnet.off-topic.geek)

Here's a quick follow-up to the matter of Arno Peters as a shameless self-promoter and his map as not novel. Here's an article that's rather well-written and goes over the general points (including why the Peters/Gall maps aren't really that (...) (22 years ago, 9-Jun-02, to lugnet.off-topic.geek)
