The Sinusoidal projection is an equal-area world map projection that has straight, horizontal parallels spaced equally at their true distances. The central meridian is straight, and the others are curves that derive from a true division of each parallel. At one time this grid was called the "Sanson-Flamsteed" projection in honor of Nicholas Sanson, the French cartographer, and Flamsteed, the English astronomer, however the name was abandoned when it was discovered that Mercator and others had used this projection at an earlier date.
