The azimuthal equidistant projection is an azimuthal map projection. It has the useful properties that all points on the map are at proportionately correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point. A useful application for this type of projection is a polar projection which shows all meridians (lines of longitude) as straight, with distances from the north pole represented correctly. The flag of the United Nations is an example of a polar azimuthal equidistant projection.
Azimuthal Equidistant Projection
To convert Azimuthal Equidistant coordinates, the following parameters have to be set:
