An azimuthal projection is a map of the world that has useful properties because all points on the map are at proportionally correct distances from its center point. One of the most common ways to use this approach is through a polar projection from the north or south.

Azimuthal Projection Advantages and Disadvantages. The azimuthal projection intercepts the Earth according to the laws of perspective and plots the traces of light onto a developable surface. When the source of light is placed in different locations, it affects the geometry of the projection.

The Azimuthal Equidistant projection is a planar projection that maintains accurate distances from the center point to any other point on the map. This projection is frequently used for polar maps, where the center point represents the North or South Pole.

An azimuthal projection geometrically maps the earth’s surface onto a plane. This is often used to show the distance from any direction to a single point. A city tourism bureau might use this projection with the city in the middle and circles around the city to indicate distance.
