Projections of the World

The Mercator projection is conformal. It preserves angular relationships but distorts area.

The sinusoidal projection is equivalent. It preserves area relationship but distorts angles.

The Molleweide projection is equivalent. It preserves area relationships but distorts angles. However, angles are not distorted as much as with the sinusoidal projection.

The Alber's equal area projection is commonly used for page size maps of the United States.

The Gnomonic projection shows the great circle as a straight line.
