Volumetric estimation of landslide-induced terrain change using conditional GAN with multi-temporal DEMs and satellite imagery

International Journal of Applied Earth Observations and Geoinformation
Estimating landslide volumes remains challenging because of the limited availability of high-resolution terrain data. Traditional methods often rely on empirical area-to-volume conversion formulas, which introduce significant uncertainties due to terrain

Quantitative Analysis of Anthropogenic Morphologies Based on Multi-Temporal High-Resolution Topography [PDF]

Remote Sensing, 2019
Human activities have reshaped the geomorphology of landscapes and created vast anthropogenic geomorphic features, which have distinct characteristics compared with landforms produced by natural processes. High-resolution topography from LiDAR has opened

Response to comment by Daley et al., on “Assessing gully erosion and rehabilitation using multi temporal LiDAR DEMs: Case study from the Great Barrier Reef catchments, Australia”

International Soil and Water Conservation Research
Daley et al. (2023a) argue that at least 10–15 years apart Digital Elevation Model (DEM) derived DEMs of Difference (DoD) surveys are needed to detect reliable geomorphic change within the gullied landscapes of the Great Barrier Reef, Australia.
