One such method is the polar azimuthal equidistant projection.
As with all azimuthal projections, angles from the tangent point are preserved.
The flag of the United Nations is an example of a polar azimuthal equidistant projection.
Many modern star chart planispheres use the polar azimuthal equidistant projection.
GeographicLib provides a class for performing azimuthal equidistant projections centered at any point on the ellipsoid.
Using a plane gives azimuthal projections.
PP3 generates maps in the azimuthal equidistant projection.
He therefore uses a completely different projection for the inset map of the north polar regions: an equidistant azimuthal projection.
It is also a modified azimuthal projection.
Other azimuthal projections are not true perspective projections:
