correct coordinates for hemisphere center? edit

I rendered a stereographic projection of the land hemisphere ([1]). This projection is suitable to show one hemisphere including adjacent areas without too much distorsion. Now it seems the landmass would be bigger if the center of the hemisphere surface is moved a bit to south. Japan at the top will drop but bigger land masses in South America will get into the hemisphere. Is that an optical illusion or are the coordinates suboptimal? --89.49.196.227 12:02, 11 January 2006 (UTC) (de:Benutzer:RokerHRO)Reply

You should go by hard numbers, not by looks, as I assume whoever originated the coordinates on this article did. ¦ Reisio 19:02, 11 January 2006 (UTC)Reply
Perhaps other Asian landmasses will drop, too. But the projection reminds me of the other question I had: Considering the parts of the continental shelves now submerged, and the statement in the article that currently, the ocean area exceeds the area of the landmass only slightly, and the area of the landmass probably exceeded the ocean area at the time of the existence of Pangaea, I wonder about the time in the Pleistocene when sea level lay as much as about 130 m lower as today: Perhaps the same had been the case back then, too?
