The effects of topographic surveying technique and data resolution on the detection and interpretation of geomorphic change

open access: yesGeomorphology, 2019
Abstract Change detection of high resolution topographic data is commonly used in river valleys to quantify reach- and site-scale sediment budgets by estimating the erosion/deposition volume, and to interpret the geomorphic processes driving erosion and deposition.

An evaluation of the effectiveness of low-cost UAVs and structure from motion for geomorphic change detection

Geomorphology, 2017
Abstract The measurement of topography and of topographic change is essential for the study of many geomorphic processes. In recent years, structure from motion (SfM) techniques applied to photographs taken by camera-equipped unmanned aerial vehicles (UAVs) has become a powerful new tool for the generation of high resolution topography.

Tapping into the Hexagon spy imagery database: A new automated pipeline for geomorphic change detection

ISPRS Journal of Photogrammetry and Remote Sensing, 2015
Abstract Declassified historical imagery from the Hexagon spy satellite database has near-global coverage, yet remains a largely untapped resource for geomorphic change studies. Unavailable satellite ephemeris data make DEM (digital elevation model) extraction difficult in terms of time and accuracy.

Geomorphic change detection using historic maps and DEM differencing: The temporal dimension of geospatial analysis

Geomorphology, 2012
Abstract The ability to develop spatially distributed models of topographic change is presenting new capabilities in geomorphic research. High resolution maps of elevation change indicate locations, processes, and rates of geomorphic change, and provide a means of calibrating temporal simulation models. Methods of geomorphic change detection (GCD),
