Map scale refers to the ratio between a unit mapped and the unit on the Earth's surface; thus, we
would want to know, for example, how many inches on the Earth's surface correspond to one inch
on the map. This is a representative fraction—it is the ratio between the map and the area being
mapped. A graphic or linear scale is a visual depiction of scale, usually portrayed as a horizontal
bar. A verbal scale also refers to the area on the surface related to the area mapped, and is
indicated linguistically, such as "one inch on the map equals five miles on the Earth's surface".
