6.4.4 Robinson projection (-Jn -JN)

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'' right6.3. The scale is true along latitudes ±38°. The projection was originally developed for use by Rand McNally and is currently used by the National Geographic Society. To use it you must enter

Again centered on Greenwich, the example below was created by this command:
