Azimuthal equidistant projection

The effective azimuthal equidistant map is a web design, in which the distance and direction of each point to the center of map is reproduced exactly. It is not a projection in the optical sense, that is, there is no projection center.

It is used for example of radio services. The antenna is at the point of contact, and you can easily determine the direction and distance to his radio partner.

The card network design can cover the entire surface of the earth, of the contact point opposite point is a circle, which it normally the screen is cut off. If one continues the illustration on this 180 -degree edge addition, regions shown to be already again, but highly distorted, played.

In polar position the meridians straight lines of latitude are mapped to circles. In transverse or general position, the latitude and circles forming complex curves. These images are not constructible with compass and straightedge.

The United Nations flag is reminiscent in its north-south dimension ( along the meridians ) to a medium Azimuthal equidistant, but its east-west dimension ( along the width circles) are corrected artistic.

Point of contact: South Pole

Point of contact: the Equator at zero meridian

Point of contact: Canberra
