Orthorectification of Full-Polarimetric Radarsat-2 Data Using Accurate LIDAR DSM
, 2013 International audienceOrthorectification using digital terrain models is a key issue for full-polarimetric complex SAR data because resampling the complex data can corrupt the polarimetric phase, mainly in terrain with relief. This research thus compared

River Research and Applications, Volume 42, Issue 8, Page 1654-1672, October 2026.ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Water Resources Research, Volume 62, Issue 10, October 2026.Abstract Accurate and continuous streamflow monitoring can support effective water resource management, yet substantial gaps persist in national streamgage networks due to operational challenges and costs. Non‐contact, image‐based techniques such as Space‐Time Image Velocimetry (STIV) offer a safe, scalable and, cost‐effective alternative for measuring

Variability of Bright Deposits in North Polar Residual Ice Cap Craters on Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract We use nearly a Mars decade of the Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE) camera observations to track surface changes in 36 small impact craters on Mars' Northern Residual Ice Cap, commonly considered to be the uppermost layer of the North Polar Layered Deposits (NPLD). Understanding the mass balance

Active Dust Devils in the Rosalind Franklin Rover Landing Site in Oxia Planum, Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The Rosalind Franklin rover will land in Oxia Planum, Mars, in the second half of 2030. The mission relies on solar arrays to provide electrical power to the rover, so knowledge about dust‐clearing rates is important for science operations.

Optimization of Ground Control Point (GCP) and Independent Control Point (ICP) on Orthorectification of High Resolution Satellite Imagery [PDF]
E3S Web of Conferences, 2019 In the rapidly evolving technology era, various survey methods have been widely used one of them by remote sensing using satellite. It is known that the satellite image recording process is covered by rides (satellites) moving over the Earth's surface at

Ecology and Evolution, Volume 16, Issue 9, September 2026.Higher meadow connectivity leads to greater plant species richness but also increases plant community similarity. Functional connectivity explains plant diversity patterns better than structural connectivity. ABSTRACT The increasing global habitat fragmentation has led to a marked decline in landscape connectivity, posing a severe threat to ...

CCTV-Based Quantification of Remaining Beach Width Associated with Wave Runup on a Sandy Beach
Journal of Marine Science and EngineeringWave runup reduces the horizontal beach buffer. At Namho Beach, South Korea, orthorectified CCTV estimation of Remaining Beach Width (RBW) and Stockdon-derived RBW sensitivity to morphology timing were evaluated separately.
