An azimuthal equidistant projection about the North Pole extending all the way to the South Pole. 

"The azimuthal equidistant projection is an azimuthal map projection. It has the useful properties that all points on the map are at proportionally 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 pole represented correctly. The flag of the United Nations contains an example of a polar azimuthal equidistant projection." ~wikipedia

The Polar Azimuthal Equidistant projection map is a type of projection map focused on the North Pole of Earth. It is a conformal map, meaning that it preserves the shape of features, however distorts them in size as they move away from the central point of the map. This map is widely used in navigation applications, as it is considered to have particularly good navigational accuracy.

The Polar Azimuthal Equidistant projection map is a projection of the North Pole onto a flat surface. The North Pole serves as the center of the map, and points away from this central point are projected in a circle, preserving the global shape of the landmasses. With this type of projection, the amount of distortion can become very large as points move further away from the central point. This type of projection is generally better for navigation than other types of projection maps, such as the Mercator projection map or the Peters projection map, which are both widely used for modern atlases and wall maps.

This type of projection is particularly good for navigational usage due to its accuracy in determining direction from the center of the map. In addition, it has even been used by airline pilots for many years as an efficient way to calculate degree measures and distances between two points, allowing them to locate coordinates in relation to the North Pole.

Although other projections have been used more often in the modern world, the Polar Azimuthal Equidistant projection, is still widely used for navigational purposes. It is considered to be the most accurate projection for short-distance and azimuthal navigation applications, making it perfect for anyone who needs to navigate across a map with accurate degree placements and distance measurements.
