1. sinusoidal projection

   A sinusoidal projection is a type of map projection used for creating two-dimensional maps of the world. It is a pseudocylindrical, equal-area projection, meaning it preserves the proportions of areas on the globe when transferring them onto a flat surface. The sinusoidal projection is distinguished by its property that meridians are mapped to vertical lines and parallels to horizontal lines. The name "sinusoidal" refers to the characteristic shape of the longitude lines, which form a sine wave pattern on the map.

1. Sinusoidal projection

   The sinusoidal projection is a pseudocylindrical equal-area map projection, sometimes called the Sanson–Flamsteed or the Mercator equal-area projection. Jean Cossin of Dieppe was one of the first mapmakers to use the sinusoidal, appearing in a world map of 1570. The projection is defined by: where φ is the latitude, λ is the longitude, and λ0 is the central meridian. Scale is constant along the central meridian, and east–west scale is constant throughout the map. Therefore the length of each parallel on the map is proportional to the cosine of the latitude, as it is on the globe. This makes the left and right bounding meridians of the map into half of a sine wave, each mirroring the other. Each meridian except the central meridian is also half of a sine wave with only the amplitude differing, giving the projection its name. Each is shown on the map as longer than the central meridian, whereas on the globe all are the same length. The true distance between two points on a meridian can be measured on the map as the vertical distance between the parallels that intersect the meridian at those points. With no distortion along the central meridian and the equator, distances along those lines are correct, as are the angles of intersection of other lines with those two lines. Distortion is lowest throughout the region of the map close to those lines.
