I have updated the gigamercator map of the earth that I had posted several months ago. If you scroll down a bit it's the second of the two.
No doubt some inaccuracies remain that I failed to correct, but overall I think it's close enough to need no further tweaking. I left the first one in the event someone preferred it over the widened second one.

I shall have a 'giga' map of North America ready in about six months (I shall be incommunicado for about that long), and look forward to working on that.
