Progressive hypsometry (PH) involves the measurement of hypsometric maxima in nested catchments whose outlets span from the lowest to the highest elevations in a mountain range. It consists of three major components: (i) segmentation of the landscape into large catchments, (ii) calculation of hypsometry along flow paths, (iii) segmentation into nested subcatchments characterized by a shared modal elevation.

How it works

• Method provides more details on the PH algorithm.
• Execution describes how to implement PH analysis.
• Code explains the Matlab scripts needed to run PH.

Use in practice

• Application shows how PH is used to reveal the role of glacial erosion in limiting the heights of mountain ranges in the tropics. Published in Cunningham et al. (2019).
• Study sites: description of regions of interest (ROIs) that are the focus of this study.
• Data describes the SRTM digital elevation model data used in these analyses.
• Analyses: all output from PH algorithm used by Cunningham et al. (2019).
• Publications: lists of all published materials (peer-reviewed papers, conference abstracts, and archived repositories) related to the study of glacial erosion in tropical mountains.
