GIS software generally uses this as the default display for convenience. This projection should never be used in print maps as usage impliesĬarelessness or ignorance of cartographic conventions. Poles, countries are distorted in width the further you move from the equator. Longitude lines are physically closer together as you move closer to the The simplest of all projections plots latitudes and longitudesĪs if the world were a grid of evenly spaced lines.
