shows how azimuthal orthographic projections can be used to calculate how much of Earth you can see at any altitude. For example, looking down from an airplane at 32,000 feet, you would be able to ...

for example, is well known for its distortions of areas at high latitudes. It turns out that another projection — the azimuthal equidistant projection – provides exactly what we want ...

“For example, Mercators projection is true to scale only along the equator, and azimuthal projection is limited to convergence of the meridians at one pole at a time. Other known systems of ...

By their calculations, the Mercator projection scores 8.296 and Winkel Tripel does better at 4.563. Their own azimuthal equidistant double-sided projection, meanwhile, scores 0.881. “We believe ...
