This projection shows all distances and directions correctly from a single point.

The azimuthal equidistant projection is a particular map projection. An example of a azimuthal equidistant projection can be seen on the United Nations flag. A useful application for this type of projection is a Polar Projection in which all distances measured from the center of the map along any longitudinal line are accurate.

This projection is used by the USGS in the National Atlas of the United States of America, and for large-scale mapping of Micronesia. It is useful for showing airline distances from center point of projection and for seismic and radio work. The United States Geological Survey (USGS) is a scientific agency of the United States government. ...

Distances and directions to all places is true only from the center point of projection. Distances are correct between points along straight lines through the center. All other distances are incorrect. Distortion of areas and shapes increases dramatically, the further away one gets from center point.

Some types of wide-angle camera lenses, known as "fisheye lenses" produce an azimuthal equidistant projection of the photographed scene onto the photographic medium. These lenses allow a much wider field of view than perspective lenses, which are limited to significantly less than 180 degrees.
