Derivation of high-quality three-dimensional surface deformation velocities through multi-source point cloud fusion: Application to Kīlauea volcano

International Journal of Applied Earth Observations and Geoinformation, 2021
Kīlauea volcano, located in the southeast of Hawai’i, is one of the most active volcanoes in the world. Multi-source InSAR measurements acquired from ascending and descending high-resolution COSMO-SkyMed SAR imagery are used to monitor Kīlauea volcano’s ...

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

Remote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

A Polarization-Power-Maximum-Based 3-D Imaging Method for Ku-Band UAV-Borne Fully Polarimetric Array InSAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Fully polarimetric array InSAR (Pol-array-InSAR) can obtain 3-D position information and the polarization scattering characteristics of targets. In this article, we propose a polarization analysis-based processing framework for the synthetic aperture ...

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Research on Alpine Glacier Deformation Monitoring Based on D-InSAR

Academic Journal of Science and Technology, 2023
Using Sentinel-1A data in 2021, the displacement of Tomur Glacier in the radar line of sight is obtained by repeated orbit differential interferometry. By introducing ice flow factor and combining glacier slope, the vertical deformation is extracted as the surface elevation change.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
