Name it Equal Earth and in the parameters box enter the following: +projeqearth +datumWGS84 +wktext Click on the OK button to save the new custom map projection. Science website, Bojan avri, Tom Patterson and Bernhard Jenny 1/3. Click on the + button to enter a new custom map project. A combination of Putniņš P4ʹ and Eckert IV projections was used as the basis. First, go to Settings > Custom Projections. It serves as an update to the Robinson projection, used to. Īs with the Natural Earth projection (2012) by Tom Patterson, a visual method was used to choose the parameters of the projection. The Equal Earth map projection was published earlier this year in the International Journal of Geographical Information Science. Therefore, they created a new projection that had more visual appeal compared to existing projections of equal areas. At that time Šavrič, Jenny, and Patterson sought alternative map projections of equal areas for world maps, but could not find any that met their aesthetic criteria. Introducing the Equal Earth ProjectionPresenter: Tom Patterson, US National Park ServiceCopresenters: Bojan Savric, Esri Bernhard Jenny, Monash UniversityTh. The decision generated controversy in the world of cartography due to this projection’s extreme distortion in the polar regions. Software for implementing the projection is easy to write and executes efficiently.Īccording to the creators, the projection was created in response to the decision of the Boston public schools to adopt the Gall-Peters projection for world maps in March 2017, to accurately show the relative sizes of equatorial and non-equatorial regions.Meridians are evenly spaced along any line of latitude.Straight parallels make it easy to compare how far north or south places are from the equator. The curved sides of the projection suggest the spherical form of Earth.The features of the Equal Earth projection include: Image created with the Geocart map projection software. Imagery is a derivative of NASA’s Blue Marble summer month composite with oceans lightened to enhance legibility and contrast. Pseudocylindrical equal-area map projection Equal Earth projection.
