     Map projections are attempts to portray the surface of the earth or a
portion of the earth on a flat surface.
Some distortions of conformality, distance, direction, scale, and area always result from this process. Some projections minimize distortions in some of these properties at the expense of maximizing errors in others. Some projection are attempts to only moderately distort all of these properties.
