Two-point equidistant projection of Asia. All distances are correct from the two points (45°N, 40°E) and (30°N, 110°E).

The two-point equidistant projection is a map projection first described by Hans Maurer in 1919.[1] Distances from any point on the map to two control points scale to the geodesic distances of the same points on the sphere. The projection is commonly used in National Geographic Society atlases for maps of Asia, and it sometimes appears in diagrams of air routes.
