Cylindrical Projections
A cylindrical projection is obtained by wrapping a large, flat plane around the globe to form a cylinder. In the following figure, the cylinder is tangent to the equator. The closer the zone of tangency the less the distortion.

The position of the cylinder can be changed. For example, in a transverse cylindrical projection, the cylinder is tangent to a meridian.
