You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round.
The new double-sided map, above, minimizes all 6 types of map distortions. The designers used an
equidistant azimuthal projection: a compromise projection, like the Winkel Tripel map (see image below), with small errors in both local shapes and areas, instead of optimizing one at the expense of the other. Antarctica and Australia are more accurately represented than in most other maps, and distances across oceans or across poles are both accurate and easy to measure, unlike one-sided flat maps.
