    • USGS 2017 AKasprak Geomorphic Process Topographic Form—Data

    Metadata Updated: October 29, 2025

    These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys." These data include (1) raster digital surface models (DSMs) from 2002, 2009, and 2013 of seven sites along the Colorado River in Grand Canyon and associated digital elevation models of difference (DoDs), (2) landscape information for each of the seven sites as vector polygons, including the site extent, area of bare sediment, flood inundation extent, and area of veegtation, (3) the locations of 113 field validation points used to assess the accuracy of the automated classification workflow during field visits in May of 2016. Also included within the dataset are the workflow software as a Python script and the fuzzy inference system (FIS) used to generate DoDs from the DSMs.
