A mathematical model that transforms the locations
of features on the earth's surface to locations on a
projection
two-dimensional surface, such as a paper map.
Since a map is an attempt to represent a spherical
object (the earth) on a flat surface, all projections
have some degree of distortion. A map projection
can preserve area, distance, shape or direction but
only a globe can preserve all of these attributes.
Some projections (for example, Mercator) produce
maps well suited for navigation. Other projections
(for example, equal-area projections, such as
Lambert) produce maps well suited for visual
analysis.
