DEFINITION

What is an Isoline Map?

An isoline map, also known as an isarithmic map, uses lines to connect point locations with similar values. A common example of this is a contour map of surface elevations. Isolines can also be used to show variables other than terrain. For example isolines are used in isobar maps of barometric pressure, isotherm maps of temperature, isobath maps of water depth, isochrone maps of travel time from a particular point, and isohyet maps of precipitation.

The isolines in this map show terrain elevations on land and ocean depths. Closer isolines indicate areas where terrain is more uneven.
