This is super neat, but it is missing my favorite projection: <a href="https://en.wikipedia.org/wiki/Transverse_Mercator_projection" rel="nofollow">https://en.wikipedia.org/wiki/Transverse_Mercator_projection</a>. To think that Mercator has the same error profile as Transverse Mercator, but we generally accept the former because of ubiquity, is very disturbing to me.
