A Two Point Equidistant projection of Asia
The two-point equidistant projection is a map projection first described by Hans Maurer in 1919[1].

Equidistant Projection
A projection that accurately preserves the distance between certain objects.

Azimuthal equidistant projections are sometimes used to show air-route distances. Distances measured from the center are true. Distortion of other properties increases away from the center point.

Other special categories of projections include equal-area, conformal, and equidistant projections.

A conformal projection primarily preserves shape, an equidistant projection primarily preserves distance, and an equal-area projection primarily preserves area.

If viewed from the North Pole, the Northern Hemisphere is a polar Azimuthal Equidistant projection. The Southern Hemisphere is divided into five equal triangular lobes that are arranged in a star pattern around the Northern Hemisphere.

For example, a planar equidistant projection centred on Montréal, would show the correct distance to any other location on the map, from Montréal only. This property is accomplished at the expense of distorting area and direction.

The projection which best fits a given country is always the minimum-error projection of the selected class. The use of minimum-error projections is however exceptional. Their mathematical theory is difficult and the equidistant projections of the ...
