azimuthal equidistant projection

One such method is the polar azimuthal equidistant projection.

Many modern star chart planispheres use the polar azimuthal equidistant projection.

PP3 generates maps in the azimuthal equidistant projection.

The flag of the United Nations is an example of a polar azimuthal equidistant projection.

Azimuthal equidistant projection, the projection that a fisheye lens creates.

GeographicLib provides a class for performing azimuthal equidistant projections centered at any point on the ellipsoid.

Concept and mathematics of the Azimuthal Equidistant Projection for the marine navigator.

The azimuthal equidistant projection is an azimuthal map projection.

This is the defining characteristic of an equidistant projection such as the Azimuthal equidistant projection.

An interactive Java Applet to study the metric deformations of the Azimuthal Equidistant Projection.

Some types of wide-angle camera lenses, known as "fisheye lenses" produce an azimuthal equidistant projection of the photographed scene onto the photographic medium.

While it may have been used by ancient Egyptians for star maps in some holy books, the earliest text describing the azimuthal equidistant projection is an 11th-century work by al-Biruni.

The symbol also appears on MJ-12 computer terminals, in this instance the globe being the azimuthal equidistant projection used by the UN flag, under the shadow of a translucent hand.

The north and south polar regions of the sky were covered by separate charts on a standard azimuthal equidistant projection, extending from the celestial poles to declination 50 degrees north and south.

Proposed by David A. Aitoff in 1889, it is the equatorial form of the azimuthal equidistant projection, but stretched into a 2:1 ellipse while halving the longitude from the central meridian:

Directly inspired by the Aitoff projection, Hammer suggested the use of the equatorial form of the Lambert azimuthal equal-area projection instead of Aitoff's use of the azimuthal equidistant projection:

For observers at moderate latitudes, who can see the sky near the celestial pole of their hemisphere better than that nearer the horizon, this may be a good reason to prefer a planisphere made with the polar azimuthal equidistant projection method.
