Equal-Area Maps

Map projections that show the correct size of landmasses are called equal-area maps. In order to show the correct size of landmasses, these maps usually distort shapes. The distortion is usually greater at the edges of the map and less at the center.

Robinson Maps

Many of the maps in this book use the Robinson projection, which is a compromise between the Mercator and equal-area projections. The Robinson projection gives a useful overall picture of the world. It keeps the size and shape relationships of most continents and oceans, but distorts the size of the polar regions.
