Multidirectional Attention Fusion Network for SAR Change Detection

Remote Sensing
Synthetic Aperture Radar (SAR) imaging is essential for monitoring geomorphic changes, urban transformations, and natural disasters. However, the inherent complexities of SAR, particularly pronounced speckle noise, often lead to numerous false detections.

AIRBORNE LASER SCANNING CHANGE DETECTION FOR QUANTIFYING GEOMORPHOLOGICAL PROCESSES IN HIGH MOUNTAIN REGIONS [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Disturbance by geomorphic processes is a key factor for current and potential plant species distributions in high mountain regions. We implemented and tested an approach for the detection, quantification, and geomorphological classification of 3D ...

Detection and attribution of hydrological changes in different climatic and geomorphic regions of China

Frontiers in Earth Science, 2023
Through large-scale hydrological simulation, understanding the impact of different climatic and geomorphic conditions on hydrological variables is valuable for water and land management. However, the related study is still a challenge due to strong environmental diversity in large scale region. The physically-based, national-scale hydrological model in

The Use of UAVs for the Characterization and Analysis of Rocky Coasts

Drones, 2021
Rocky coasts represent three quarters of all coastlines worldwide. These areas are part of ecosystems of great ecological value, but their steep configuration and their elevation make field surveys difficult.

Assessing Geomorphic Change in Restored Coastal Dune Ecosystems Using a Multi-Platform Aerial Approach

Remote Sensing, 2021
Uncrewed aerial systems (UAS) provide an effective method to examine geomorphic and vegetation change in restored coastal dune ecosystems. Coupling structure-from-motion (SfM) photogrammetry with RGB orthomosaic imagery allows researchers to characterize

Align, Perturb and Decouple: Toward Better Leverage of Difference Information for RSI Change Detection [PDF]

International Joint Conference on Artificial Intelligence, 2023
Change detection is a widely adopted technique in remote sense imagery (RSI) analysis in the discovery of long-term geomorphic evolution. To highlight the areas of semantic changes, previous effort mostly pays attention to learning representative feature

Quantifying co-seismic and post-seismic erosion using geomorphic change detection following the Mw 7.8 Kaikōura earthquake, New Zealand

<p dir="ltr">Mountain belts are built by uplift and deformation, the associated earthquakes commonly triggering widespread and destructive landsliding across the landscape. The quantification of co-seismic landslide erosion is important because post-seismic observations reveal enhanced mass wasting and fluvial transport of sediment following a ...

Similarity and Change Detection of Relief in a Proglacial River Valley (Scott River, SW Svalbard)

Remote Sensing, 2023
This study focuses on contemporary geomorphic changes in the proglacial valley floor of the Scott River catchment (northwest of Wedel Jarlsberg Land, southwestern Spitsbergen). The similarity and variability of landforms along the entire 3.3 km length of

M3C2-EP: Pushing the limits of 3D topographic point cloud change detection by error propagation

Isprs Journal of Photogrammetry and Remote Sensing, 2021
The analysis of topographic time series is often based on bitemporal change detection and quantification. For 3D point clouds, acquired using laser scanning or photogrammetry, random and systematic noise has to be separated from the signal of surface ...

Hydrogeomorphological analysis and modelling for a comprehensive understanding of flash-flood damage processes: the 9 October 2018 event in northeastern Mallorca [PDF]

Natural Hazards and Earth System Sciences, 2020
A flash-flood event hit the northeastern part of Mallorca on 9 October 2018, causing 13 casualties. Mallorca is prone to catastrophic flash floods acting on a scenario of deep landscape transformation caused by Mediterranean tourist resorts.
