Projection
- The process of showing a round globe on a flat surface is called a projection. Think about this: Have you ever tried to flatten out an orange peel? What happens when you try to make the pieces line up perfectly to make them flat? You will have to squish and tear and move all the pieces around.

A drawing of a curved object (such as Earth’s surface) onto a flat piece of paper is called a projection. Over the centuries, mapmakers have come up with many different types. All distort the relative size of Earth’s features. The most common map used these days is the Mercator projection. It’s may even be on your classroom wall. Though good, it ha...
J. Richard Gott and David Goldberg are astrophysicists. Gott works at Princeton University in New Jersey. Goldberg studies galaxies at Drexel University in Philadelphia, Penn. When Goldberg was in graduate school, Gott was one of his teachers. About a decade ago, the two developed a system for scoring the accuracy of maps. They based scores on six ...
The ArXiv post on the new approach to mapping spheres was not peer reviewed. This means other scientists have yet to judge it. But Thomas is not the only scientist excited about its prospects. “I think it would be really neat to make a version of the map that shows the arrangements of the continents in periods such as the Triassic and the Jurassic,...
A map projection allows us to turn the round Earth (or orange) into a flat surface. Calculations (math equations) determine where each point on Earth would be on the new, flat surface, and each spot on the globe has a unique spot on the flat surface.
Feb 25, 2021 · You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round.
An important step in the simplification is taking the surface of Earth and presenting it on a flat (planar) surface. When Earth’s surface is converted (projected) from 3 dimensions to 2 dimensions, there are trade-offs. In addition to going from round (and 3-D) to flat, the representation must be reduced in size.

Wait a minute – you just realize Earth is round, so how do you create an accurate flat map? Throughout history, cartographers all around the world have found different methods for creating flat maps of Earth. None can represent reality exactly, but each is useful for specific purposes.
