The following globes can be constructed for personal use. In some cases they are free on-line and in others, they can be ordered via information provided at the linked sites.
The RealEarth GlobeMap is a 14-faceted teaching tool. There are two current editions of the GlobeMap a 12" diameter model and a 5" diameter model. The RealEarth web site contains ordering information, and extensive teachers resources. The GlobeMaps can be ordered by individuals and schools and there are also line map globes on the web site that may be downloaded, printed, and pasted together for non-commercial use.
Originally posted for Valentine's Day. A choice of cordiform (heart shaped) map projections. On the left is the Werner and to the right is the Bonne. Both are pseudoconic, equal area projections. Click on the maps for full sized versions. I liked the Laskowski Minimum Error projection display by Paul B. Anderson so much that I decided to impose on him for this pair!
Can you identify the map projection? From the expert, John P. Snyder, "I think it is an equatorial stereographic projection, which appears to suit the cartography of the period -- note the eastern coastline of Asia -- but more technically is indicated by the fact that the parallels, most notably the 80th, intersect the outer meridians, and other meridians, at right angles. On the globular projection, not used much for such published maps until the 19th century, the parallels are usually not at right angles, most visibly where the 80th parallel strikes the 90th meridians from center."
Can you identify this projection and the dataset used? Information and graphic are kindly provided by Paul B. Anderson. Solution
