World Map Projections

CaptionResourceCreateNotebook

See how the world, as well as individual countries, are rendered with different map projections. Each projection corresponds to a certain choice of how to "unwrap" the approximately spherical Earth onto a plane. The "center" of the projection determines what point on the Earth will be drawn in the center of the image.

Initialization CodeResourceCreateNotebook

If you provide initialization code, include a SaveDefinitions->True option in the Manipulate.
