- To make accurate maps of places, a projection of Earth’s surface to a plane (flat surface) is required1. There are two basic methods that mapmakers use in projections2:
- The mapmaker “slices” the sphere in some way and unfolds it to make a flat map. This is like flattening out an orange peel.
- The mapmaker can look at the sphere from a certain point and then translate this view onto a flat paper.

In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. Projection is a necessary step in creating a two-dimensional map and i…
