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.

Projections: Maps are called projections because map-makers have to project a 3-D surface onto a 2-D map. A projection is a representation of one thing onto another, such as a curved 3-Dimensional surface (like the Earth) onto a flat 2-Dimensional map. ... There are 3 major types of projections: cylindrical, conic, and planar.
