1570 Cossin produces a world map based on the projection with verifiably sinusoidal meridians. 1606 Jodocus Hondius Amsterdam uses the projection for maps of Africa and South America, presumably leading to the name Mercator equal-area. ca. 1650 Nicolas Sanson d'Abbeville uses the projection extensively for maps of all continents.

The Sinusoidal projection, also known as the Sanson-Flamsteed projection, is an equal-area pseudocylindrical projection that minimizes distortion in the east-west direction near the equator. It is often used for world maps that prioritize accurate area representation, such as climate or vegetation maps .

Sinusoidal projection of the world. The sinusoidal projection with Tissot's indicatrix of deformation Jean Cossin, Carte cosmographique ou Universelle description du monde, Dieppe, 1570. 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

Sinusoidal Projection Formerly used for other continental maps and star maps. Combined with Mollweide projection to develop other projections such as the Homolosine and the Boggs. Origin. Developed in the 16th century. Used by J. Cossin in 1570 and by J. Hondius in Mercator atlases of the early 17th century. Often called Sanson-Flamsteed

The Sinusoidal Projection. This projection, also known as the Sanson-Flamsteed projection, and the Mercator Equal-Area projection, is the simplest pseudocylindrical equal-area projection. These illustrations, plotted by computer, are from An Album of Map Projections, U. S. Geological Survey Professional Paper 1453, by Voxland and Snyder

The sinusoidal projection is an equal-area projection given by the transformation x lambda-lambda_0cosphi 1 y phi. 2 The inverse formulas are phi y 3 lambda lambda_0xcosphi. Snyder, J. P.

While there were rudimentary projections with straight parallels used as early as the 2nd century B.C. by Hipparchus, the first such projection still used for scientific mapping of the sphere is the Sinusoidal. This projection fig. 54 used for world maps as well as maps of continents and other regions, especially those bordering the Equator

The sinusoidal map projection is shown centered on Greenwich. Projection properties. The subsections below describe the sinusoidal projection properties. Graticule. Sinusoidal is a pseudocylindric projection. The equator and the central meridian are projected as straight lines, where the projected equator is two times as long as the central

The Sinusoidal Projection is a map projection that represents geographic features accurately in terms of area, making it useful for thematic mapping. This projection uses sinusoidal curves to create a visually appealing layout that maintains the proportion of areas while distorting shapes, particularly towards the edges of the map.
