| Map Projection is a method of representing a spherical body (such as the Earth) on a two-dimensional surface (such as a computer screen). There are many different projections available, each of which represents the spherical curves of Earth in different ways. Because every projection distorts the data in some areas to a certain degree, choosing the right projection for the maps you want to view is important. For example, if you will be creating maps of a very specific local region of the United States, you might want to use a State Plane projection which focuses on that region. This will minimize distortion of the region you're working in at the expense of distorting other areas of the world. Because you will not need to display those other areas of the world, the distortion there is acceptable. For more information about the concept of projecting map data, we recommend [[http://en.wikipedia.org/wiki/Map_projection|this Wikipedia article]]. | Map Projection is a method of representing a spherical body (such as the Earth) on a two-dimensional surface (such as a computer screen).
