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.

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

Distribution of furrows (yellow lines) projected in azimuthal equidistant map centered at 20°S 180°W (plate A) and its exactly opposite point, 20°N, 0°W (plate B). White regions indicate the ...
