What type of projection is best to map polar regions?

The best type of projection to map polar regions is the azimuthal projection. This projection is characterized by its ability to maintain accurate bearings from a central point, making it particularly useful for mapping polar areas where the North or South Pole is at the center of the map.

In an azimuthal projection, distances and directions from the central point are accurately represented, which is especially beneficial for navigation and analysis in polar regions. The projection shows one hemisphere (or a specific area) in a way that preserves these properties, allowing for a clear representation of spatial relationships that is ideal for regions situated at high latitudes.

While other projections, such as cylindrical and conic projections, can represent the polar areas, they often introduce significant distortion, especially in terms of shape and distance, which becomes more pronounced the closer one gets to the poles. Equal-area projections, while good for representing area proportions accurately, do not necessarily provide realistic representations of direction or distances, which can be crucial for polar navigation and analysis. Therefore, the azimuthal projection's unique characteristics make it the most suitable choice for mapping polar regions effectively.
