Flexi Says: A map projection is a way to show a three-dimensional figure in two dimensions. There are many types of projections. Each uses a different way to change three dimensions into two dimensions. There are two basic methods that the mapmaker uses in projections: The mapmaker “slices” the sphere in some way and unfolds it to make a flat map. This is like flattening out an orange peel. Or, the mapmaker can look at the sphere from a certain point and then translate this view onto a flat paper. Some commonly used projections are Mercator Projection, Conic Projection, Gnomonic Projection, and Robinson Projection.
