*Abstract*

Tom Patterson will discuss the making of the Natural Earth, Natural Earth
II, and Patterson projections in collaboration with Bernhard Jenny and
Bojan Savric, Oregon State University. The effort began with the
development of Flex Projector, a free, cross-platform application for
designing new world map projections via graphical controls. With this
software was designed to improve the venerable Robinson projection. The
resulting Natural Earth projection, also a compromise pseudo-cylindrical
projection, has better distortion properties, a taller height-to-width
aspect ratio, and slightly rounded corners where the pole lines and lateral
meridians meet. The Natural Earth II is a follow up projection with a
highly-rounded shape that took its design inspiration from the Mollweide.
The third projection, the eponymous Patterson, is a cylindrical derived
from the Miller, but with significantly less polar distortion. All three
new map projections are intended for general-purpose mapmaking.
