List of Isolines

Isolines

Isolines are often used on maps to represent points of equal value. This is a list of some common (as well as obscure) types of isolines. The prefix "iso-" means "equal."

A line representing points of equal recurrence of auroras

* Isocheim

A line representing points of equal mean winter temperature

* Isochrone

A line representing points of equal time-distance from a point, such as the transportation time from a particular point

* Isodapane

A line representing points of equal transport costs for products from production to markets

* Isodose

A line representing points of equal intensity of radiation
