This south-at-the-top map is a great educational tool. It challenges basic notions of ''up'' and ''down.'' True ''up'' from our standpoint on the earth, is away from the center, and the earth in space has no inherent up or down. To emphasize this point, this map includes an inset, which shows global views from various angles. In addition, other inset maps show examples of a variety of projections with notes on their merits and limitations.
