Isochron Map

Definition - What does Isochron Map mean?

Isochron Map is a map that displays areas related to isochrones between two different travel points. The map has some connecting points that depict something that has occurred. It is most commonly used in hydrology and transport planning. Moreover, it is also regarded as a counter map of similar values of distinct travel points between the selected seismic reflection events. It is used to provide the information about the thickness of seismic data. It is a time-structured map used to generate isopach maps and elevation structure maps.

Petropedia explains Isochron Map

Since 1887, Isochron Maps have been used for transportation planning. Before Isochron Maps were beings used, Isochronic Postal charts and Isochronic Passage Charts were used to describe the same information. They are commonly used in the United Kingdom for development control. With technical advancements, the maps are dynamically generated for use in websites. An Isochron Map has a number of uses such as:

  • It is used in hydrology to describe the time taken for run-off water to reach a lake through a drainage basin.
  • It is used in transportation planning to describe time-based travel information for different modes of transportation.
