A map projection is a rule that sends every point of the globe, given by its latitude and longitude, to a point of a flat map. On a Mercator projection, the parallels and the meridians are straight lines crossing at right angles, and the shape of every small region is kept, but areas are enlarged more and more towards the poles. On an equal-area projection, every region keeps its true area compared with the others, but shapes are bent, more and more towards the edges of the map.
