Measuring Sand Dune Migration Rates With COSI-Corr and Landsat: Opportunities and Challenges [PDF]

open access: yesRemote Sensing, 2019
It has been over a decade since COSI-Corr, the Co-Registration of Optically Sensed Images and Correlation, was first used to produce a raster map of sand dune movement, however, no studies have yet applied it to the full Landsat archive.

Determination of Mass Movements in Slow-Motion Landslides by the Cosi-Corr Method [PDF]

open access: yesGeomatics, Natural Hazards and Risk, 2018
Landslides bring damage to urbanization and cause negative effects on the quality of agricultural and forest areas and rivers. Therefore, it is of vital importance to detect displacements in landslide areas causing the loss of life and property ...

Estimation of Surface Ice Velocity of Durung Drung Glacier, Western Himalaya Using COSI-Corr From Landsat Images

open access: yesEgyptian Journal of Remote Sensing and Space Science
Glaciers all over the world have been experiencing recession at varying rates. Alterations in glacial retreat, volume, and mass have direct implications for sea level rise and have implications for the overall health of glaciers.

Co-registration of Optically Sensed Images and Correlation (COSI-Corr) applications in ground deformation measurement [PDF]

open access: yes地震科学进展
Traditional optical remote sensing change detection methods can’t eliminate the error induced by the imaging system and terrain, due to the need for external information from global positioning system (GPS) measurements.

Co-Registration of Optically Sensed Images and Correlation (COSI-Corr): An Operational Methodology for Ground Deformation Measurements [PDF]

open access: yes2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
Recent methodological progress, co-registration of optically sensed images and correlation, outlined here, makes it possible to measure horizontal ground deformation from optical images on an operational basis, using the COSI-Corr software package. In particular, its sub-pixel capabilities allow for accurate mapping of surface ruptures and measurement ...

Application of Sentinel-1 and-2 Images in Measuring the Deformation of Kuh-e-Namak (Dashti) Namakier, Iran

open access: yesRemote Sensing, 2021
Kuh-e-Namak (Dashti) namakier is one of the most active salt diapirs along the Zagros fold–thrust belt in Iran. Its surface deformation should be measured to estimate its long-term kinematics.

Glacial Lake Outburst Flood Hazard and Risk Assessment of Gangabal Lake in the Upper Jhelum Basin of Kashmir Himalaya Using Geospatial Technology and Hydrodynamic Modeling

open access: yesRemote Sensing, 2022
Climate warming-induced glacier recession has resulted in the development and rapid expansion of glacial lakes in the Himalayan region. The increased melting has enhanced the susceptibility for Glacial Lake Outburst Floods (GLOFs) in the region.

Assessment of Aeolian Activity in the Bodélé Depression, Chad: A Dense Spatiotemporal Time Series From Landsat-8 and Sentinel-2 Data

open access: yesFrontiers in Environmental Science, 2022
There are several hotspots of dust production in the central Sahara, the Bodélé Depression (BD) in northern Chad is considered the largest source of aerosol dust worldwide, with the fastest Barchan dunes that migrate southwesterly.

Spatiotemporal Variability of Velocity and Influence of Glacier Thickness Using Landsat Imagery: Hunza River Basin, Karakoram Range

open access: yesIEEE Access, 2021
The Karakoram Anomaly has been intensively investigated, but the factors that control this anomaly, such as the glacier velocity, topography, and mass balance, remain poorly understood.

Glacier Surface Velocities in the Chandrabhaga Massif, Western Himalaya (India) Derived Using COSI-Corr From Landsat Images [PDF]

open access: yes, 2021
Abstract Himalayan glaciers act as a storehouse of freshwater outside the polar region and sustain the flow of several Asia’s major river systems, such as the Ganges, Indus, and Brahmaputra. Glaciers in High Mountain Asia are likely to be affected by climate change, posing a threat to the future water supply.
