Bivariate Gamma Distributions for Image Registration and Change Detection [PDF]

, 2007
This paper evaluates the potential interest of using bivariate gamma distributions for image registration and change detection. The first part of this paper studies estimators for the parameters of bivariate gamma distributions based on the maximum ...

Geomorphic Change Detection Software

, 2020
The GCD software was developed primarily for topographic change detection in rivers, but will work for simple, raster-based change detection of any two surfaces.

Geomorphic time series reveals the constructive and destructive history of Havre caldera volcano, Kermadec arc

Frontiers in Earth Science
Monitoring active seafloor processes requires repeated, comparable surveys to enable change detection. The change detection of the deep ocean floor, however, is rare due to a paucity of repeat data at an appropriate resolution.

Comment on “Assessing gully erosion and rehabilitation using multi temporal LiDAR DEMs: Case study from the Great Barrier Reef catchments, Australia” by Khan et al., 2023

International Soil and Water Conservation Research
Geomorphic change detection (GCD) using high resolution topographic data can provide important insights into geomorphological systems. However, considerations must first be given to the mechanisms and dynamics producing landscape change when considering ...

A conceptual connectivity framework for understanding geomorphic change in human-impacted fluvial systems

, 2017
Human-induced landscape change is difficult to predict due to the complexity inherent in both geomorphic and social systems as well as due to the coupling relationships between them.

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
Millions of dollars are being spent on gully rehabilitation to help reduce excess fine sediment delivery to the Great Barrier Reef (GBR). There is an urgent need for (i) prioritisation of active gullies for rehabilitation and (ii) the development of ...

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.

Geomorphic Change Detection Using Cost-Effective Structure-from-Motion Photogrammetry: Evaluation of Direct Georeferencing from Consumer-Grade UAS at Orewa Beach (New Zealand) [PDF]

Photogrammetric Engineering & Remote Sensing, 2020
Unmanned aerial systems (UAS) and structure-from-motion photogrammetry are transforming the way we produce topo- graphic data, with applications covering many disciplines in the geosciences, including coastal studies. To overcome limitations of ground control points (GCPs), we evaluate direct georeferencing (DG) of consumer UAS imagery for the cost ...
