What projection to use for many parts of the world
Hiking & ActivitiesWhich projection is suitable for whole world? Goode’s homolosine map projection was developed by John Paul Goode in 1925. One of the main key features of a Goode homolosine projection is its ability to minimize distortion for the entire world. Continents shown on Goode’s Homolosine maps are proportionally sized correctly to each other. What map
