This has been on my back-burners for a while... If anyone is interested in some (crude) antipodal (Earth-countries) map overlaps, I've put up a web-page with a few pictures... http://members.home.net/hahaj/antipodal.html The Mathematica WorldData.m document sources the country polygonal-point data (on which the country-plots are based): "These data are derived from what was originally a CIA database, released into the public domain by the Freedom of Information Act. I acquired a copy of these data, and rearranged them to the form below. The copy I found was from the Amiga Fish disks, a public-domain distribution of software for the Amiga computer, under the name WorldDataBank. Note that these data (in the original format) are available at higher resolution from this source." I've had a look at the "original format" of a Net copy of WorldDataBank and didn't see anything that I knew how to extract. It's been voiced before but I'll say it again: It would be nice to have more accurate data-points for Mathematica's WorldPlot.
