A map that preserves distance (or equidistant) will display the world so that a measured distance on the projection will be the same as on the globe. An equal-area map projection will distort shape, angle, scale, or any combination of the three. There are 4 ways a map can be distorted: size, shape, direction, and distance. A Conformal map projection does this by having the graticule lines intersect in 90 degree angles, so that all displayed geographic phenomena are drawn at the exact angle and shape as they are on the globe. The Mercator projection, for example, distorts Greenland because of its high latitude, in the sense that its shape and size are not the same as those on a globe. )robinson projection . One easy way to understand how map projections alter spatial properties is to visualize shining a light through the earth onto a surface, called the projection surface.
