NEW! Watch the 2018 NACIS video on designing the Equal Earth projection. August 7, 2018 – The Equal Earth map projection is a new equal-area pseudocylindrical projection for world maps. We created it to provide a visually pleasing alternative to the Gall-Peters projection, which some schools and organizations have adopted out of concern for fairness—they need a world map showing continents and countries at their true sizes relative to each other. In addition to being rigorously equal-area throughout, other Equal Earth features include: • An overall shape similar to that of the Robinson projection. (The Robinson, although popular and pleasing to the eye, is not equal-area as is the Equal Earth projection). • The curved sides of the projection suggest the spherical form of Earth. • Straight parallels that make it easier to compare how far north or south places are from the equator. • Meridians are evenly spaced along any given line of latitude. • Easy-to-implement code that runs efficiently in software. |

For more about the design and development of the Equal Earth projection, refer to this article published in the International Journal of Geographical Information Science. This PDF has mathematics and implementation details. Developers: You can implement the Equal Earth projection in your software by downloading the JavaScript code here. Cartographers: The Equal Earth projection is starting to appear in mapping and GIS software. It is now available in Flex Projector, ArcGIS Pro 2.3, and QGIS 3.4. With these software applications you can make maps from vector and image geospatial data. Bloggers and reporters: You are welcome to use these images with your stories about the Equal Earth projection. |
