LiDAR, UAV SfM and geomorphic change detection in small quarry and landslide interactions

2021
<p>Quarry activity triggers landslides, especially in small, unplanned, and not maintained quarries. Given the size of these small quarries that are very frequent in the rural areas of north-eastern Romania, their study is difficult because of the lack of topographic data.

Application of geomorphic change detection (GCD) on tufa digital elevation models (DEMs) of submillimeter resolution – case study National park Krka, Croatia

Zeitschrift für Geomorphologie, 2021
Repeat measurements are often used to monitor geomorphological changes on different scales. Such measurements can produce interval digital elevation models (DEMs) which differenced generate distributed maps of elevation changes. One of the most popular tools for creating these models is the Geomorphic Change Detection (GCD) tool.

Debris-Flow Monitoring and Geomorphic Change Detection Combining Laser Scanning and Fast Photogrammetric Surveys in the Moscardo Catchment (Eastern Italian Alps)

2014
Monitoring debris-flow prone catchments and collecting field data is of extreme importance for improving the knowledge and therefore the management of such hazardous phenomena. High-resolution Digital Elevation Models (DEMs) have recently established as an important tool for the study of geo-hydrological and geomorphological processes.

Optical and radar remote sensing improve DEM-based geomorphic change detection in semi-arid landscapes

2023
Accurate measurements of geomorphic change are necessary to improve quantitative and conceptual models in geomorphology. New generation high-resolution topography (HRT) is enabling increasingly accurate quantification of surface change via differencing of fine scale (<1 m) multi-temporal digital elevation models (DEMs).

Dealing with uncertainties in assessing geomorphic change. Spatially estimating structure-from-motion precisions using a block-resampling approach.

, 2021
Structure-from-Motion – Multi-View Stereo (SfM-MVS) has become a widely used approach in the study of Earth surface processes to reconstruct high-resolution topography (HRT) models.
