1. A method of incorporating in at least one electronic graphics file at least one first mapping system in at least one storage medium, comprising: storing, in the at least one storage medium, mapping system information in the at least one electronic graphics file, the mapping system information comprising projection information and datum information, wherein the projection information comprises mathematical information that transforms coordinates of features on the Earth's three-dimensional surface to coordinates on a two-dimensional surface, and wherein the datum information comprises parameters and control points used to accurately define a three-dimensional shape of the Earth; storing, in the at least one storage medium, geo-registration information in the at least one electronic graphics file, the geo-registration information comprising information used to accurately transform the coordinates from the two-dimensional surface to a coordinate system of the electronic graphics file; and storing, in the at least one storage medium, neatline information describing geographic boundary information of a region of the coordinate system of the electronic graphics file to which the geo-registration applies; wherein the mapping system information, the geo-registration information, and the neatline information enables graphics information to be self-contained in the at least one electronic graphics file and to be associated with map information in at least one second mapping system, the at least one second mapping system different from the at least one first mapping system.
