Patterson Cylindrical Projection


The Patterson, a new projection designed for general-purpose mapmaking, is an alternative to other cylindrical projections (see comparisons below). It falls between the popular Miller 1, which exaggerates the size of polar areas, and the Plate Carrée, which compresses the mid latitudes. With its relatively compact 0.57 height-to-width aspect ratio, the Patterson fits nicely in printed reports, web pages, or any project needing a world map with a rectangular format.
