sinusoidal projection

URL copied Share URL
  1. [map projections] An equal-area pseudo-cylindrical projection, equidistant in the east–west direction and in the north–south direction along the central meridian, but only in these directions; developed by French hydrographer Jean Cossin in 1570. Sometimes called the Sanson-Flamsteed projection, the projection is also attributed to 17th century French cartographer Nicolas Sanson and British astronomer John Flamsteed, who used the sinusoidal projection for global atlases and star maps respectively.
