Natural Earth projection

The Natural Earth projection is a pseudocylindrical projection with moderate distortion. It has distinguishing rounded corners, where the pole lines and bounding meridians meet. It was designed in Flex Projector by Tom Patterson in 2007.

Natural Earth II projection

The Natural Earth II projection is another pseudocylindrical projection with compromise distortion designed by Tom Patterson in Flex Projector. It has a highly rounded shape, which resembles an elongated globe.

Patterson projection

The Patterson projection, a new projection designed for general-purpose mapmaking, is an alternative to other cylindrical projections. It falls between the popular Miller 1 cylindrical, which exaggerates the size of polar areas, and the Plate Carrée, which compresses the mid latitudes. It was designed by Tom Patterson in Flex Projector.

Adaptive Composite Map Projections

Adaptive composite map projections combine several projections; they adapt the map's geometry to scale, to the map's height-to-width ratio, and to the central latitude of the displayed area. The multiple projections are combined, and their parameters are adjusted to create seamless transitions. It was introduced by Bernhard Jenny.

INTERACTIVE VIDEO MAP: A Year in the Life of Earth’s CO2

A Year in the Life of Earth’s CO2 is an interactive video map that visualizes the global atmospheric carbon dioxide distribution in 2006. The map was created by Bernhard Jenny and his team; it uses the adaptive composite map projections framework.

Aspect-Adaptive cylindrical projection

The compromise aspect-adaptive cylindrical map projection adjusts the distribution of parallels to the height-to-width ratio of a map. The polynomial expressions define the projection for any height-to-width ratio between 0.3 and 1. The Compact Miller projection (on the right) is a special case of the aspect-adaptive cylindrical projection with the height-to-width ratio of 0.6.

Hufnagel's map projection family

In 1989, Herbert Hufnagel introduced a family of pseudocylindrical equal-area projections, which includes the Mollweide, Eckert IV and Wagner IV projections, as well as eight new projections introduced by Hufnagel himself.
