Adaptive Composite Map Projections

I invented adaptive composite map projections, which are an alternative to the web Mercator projection used by Google Maps and all other major web maps. They show large landmasses without area distortion, and the centre of a world map can be adjusted interactively.

Selecting Map Projections

The interactive Projection Wizard helps cartographers select a map projection that is optimized for the geographical area and the map format. Programming by Bojan Šavrič. We also investigated user preferences and guidelines for selecting projections for world maps.

Flex Projector

Flex Projector is a software application for designing new map projections for world maps. New projections can be generated from scratch, or existing ones can be changed, or two source projections can be mixed to create a new one.

New Projections for World Maps

The Natural Earth I and II are new projections with rounded corners where the pole lines and bounding meridians meet. The Patterson Cylindrical projection was developed in a similar way, and all projections are now included in ArcGIS.

Patterson Cylindrical


In 1989, Herbert Hufnagel introduced a generalization of the Mollweide projection, resulting in a family of pseudocylindrical equal-area projections. The Mollweide, Eckert Ⅳ and Wagner Ⅳ projections are members of this family. Explore Hufnagel’s projection with this interactive tool at http://projectionwizard.org/Hufnagel.html
