The Robinson projection, presented by the American geographer and cartographer Arthur H. Robinson in 1963, is a modified cylindrical projection that is neither conformal nor equal-area. Central meridian and all parallels are straight lines; other meridians are curved. It uses lookup tables rather than analytic expressions to make the world map “look” right 1. The scale is true along latitudes 38° north and south. The projection was originally developed for use by Rand McNally and is currently used by the National Geographic Society.
n[lon0/]scale or N[lon0/]width
The projection is set with n or N. The central meridian is set with the optional lon0, and the figure size is set with scale or width.
Robinson provided a table of y-coordinates for latitudes every 5°. To project values for intermediate latitudes one must interpolate the table. Different interpolants may result in slightly different maps. GMT uses the interpolant selected by the parameter GMT_INTERPOLANT in the gmt.conf file.
