Mountain ordering : a method for classifying mountains based on their morphometry
  • Mountain ordering : a method for classifying mountains based on their morphometry
  • Classification ; Fractal geometry ; Geomorphometry ; Hokkaido ; Japan ; Methodology ; Mountain ; Relief
  • A new method for defining the extent of a mountain, mountain ordering, is proposed, and is used to examine the morphological characteristics of a set of ordered mountains in northern Japan. As an example of geomorphometry based on the method
  • of mountain ordering, mountain order and the number, area and height for mountains of each order were determined for these mountains.

Vertical distance, releif energy and altitudinal limits as distinguishing features of high mountains
  • Vertical distance, releif energy and altitudinal limits as distinguishing features of high mountains
  • Altitude ; Classification ; High mountain ; Mountain ; Relief
  • Mountain constitute the Earth's third pole, because they hypsometrically repeat the climate zones as far as the Arctic within smallest space. For this reason, the vertical distance and relief energy are characteristic and distinguishing features
  • of any classification of mountains. But when taking such basic features into consideration, geomorphologists, glaciologists and geobotanists have to define mountain-typological threshold values in a new way. - (IfL)
