The azimuthal orthographic is thousands of years old. In the first century, Ptolemy described how a geographer named Hipparchus used the projection, which he called the analemma, to map the globe.

Their own azimuthal equidistant double-sided projection, meanwhile, scores 0.881. “We believe it is the most accurate flat map of Earth yet,” the trio write.

“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.

This “azimuthal” polar projection is depicted on the United Nations flag. North America was prominent on the initial 1945 UN flag (which had the longitude line 90 degrees west pointing upwards).

Known as a "planisphere," the map is aligned in a “north polar azimuthal projection,” meaning that the North Pole is at its center. When he published his work in a four-volume, ...

Map the region’s boundary using the azimuthal equidistant projection, initially guessing where the geographic center might be, and centering the map there.

Factum Arte has also made an animation of a waterless 3-D globe, along with their five 3-D relief models based on historical maps. The first, known as the “Azimuthal Projection,” evokes the ...

Here, we assume that the azimuthal anchoring at the PVA surface is relatively strong against the grating surface. [9] A φ is determined by the balance between the torque due to the bulk and that due ...
