A. In a strict sense, a line or surface on which some mathematical function has a constant value. It is sometimes distinguished from a contour by the fact that an isopleth need not refer to a directly measurable quantity characteristic of each point in the map area; e.g., maximum temperature of a particular point b. A general term for a line, on a map or chart, along which all points have a numerically specified constant or equal value of any given variable, element, or quantity (such as abundance or magnitude), with respect to space or time; esp. a contour. Etymol. Greek isos, equal, + plethos, fullness, quantity, multitude. Syn:isogram; isoline;isontic line; isometric line e.g., maximum temperature of a particular point. (references)

Different types of isopleth are given different names according to the nature of the quantity involved:

"iso" can be replaced with "isallo" to give it the meaning of a line connecting points where some variable has changed at the same rate during some time period.
