Rationale

Several reasons support the name sinusoidal:

  • Alternatives attribute Sanson and/or Flamsteed, yet neither developed the projection.
  • The originator is not known with certainty.
  • The name is descriptive.
  • The projection is so obvious as to render attribution meaningless.
  • Modern texts surveyed preferred sinusoidal by a 1.25¹: 1² margin. As the 20th century progressed we see a strong shift toward sinusoidal. (Steers and Mainwaring did not commit to one name.)

Chronology of projection development

  • 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.
  • ca. 1675: John Flamsteed (England) uses the projection extensively in astronomical maps and praises its accuracy in correspondence with Isaac Newton.
