Azimuthal Equidistant
The Azimuthal Equidistant projection is neither an equal-area nor a conformal projection. The outer meridian of a hemisphere on the equatorial aspect is a circle. Distances and directions measured from the center are true. We recommend using the Azimuthal Equidistant projection for coordinate systems in which distances are measured from an origin. The Azimuthal Equidistant projection is used in oblique aspect for atlas maps of continents, and in world maps for aviation.The "Azimuthal Equidistant" projection has the following parameters:
