What major impact does latitude have on projection choice?

Latitude has a significant impact on the choice of map projections primarily because different projections manage distortion in varying ways depending on the latitude being represented.

In map-making, distortion refers to the inaccuracies that occur when representing the curved surface of the Earth on a flat surface. Certain projections are designed to minimize distortion in specific areas or for specific latitudes. For instance, projections like the Mercator preserve angles well but distort areas, particularly as one moves toward the poles. This means that the Mercator is often better suited for navigation because it maintains straight lines for compass directions, but it can misrepresent the size of landmasses at high latitudes.

On the other hand, projections such as the Albers Equal Area or the Lambert Conformal Conic are better suited for representations of mid-latitudes and prioritize accurate area preservation or shape distortion respectively. Thus, understanding the latitude of the area of interest helps in selecting a projection that minimizes distortion for the specific geographic context, ensuring that the most relevant and accurate visual information is presented for the intended use of the map.

This context illustrates that distortion levels in the map are crucial in determining which projection is most suitable, directly informed by the latitudinal context of the mapping endeavor.
