Orthorectification and DSM generation with ALOS-Prism data in urban areas [PDF]

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
In this paper different methods for deriving digital surface models (DSM) from ALOS Prism three line stereo images are generated and analyzed. The methods used are classical hierarchical stereo matching with forward intersection and two different dense stereo methods.

Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...

Reconnaissance Investigation of Sedimentation Patterns in a Small Modern Anthropogenically Influenced Inlet, Otūwhero Estuary, Abel Tasman National Park, New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
The structurally controlled Otūwhero estuary on the SE boundary of Abel Tasman National Park is a small partially filled incised valley. The small size, limited number of fluvial inputs, accessibility and surrounding land use made it an ideal candidate on which to investigate potential climate‐induced estuarine behaviour. Surficial sediment samples and

Georeferenced UAV Localization in Mountainous Terrain Under GNSS-Denied Conditions

Drones
In Global Navigation Satellite System (GNSS)-denied environments, unmanned aerial vehicles (UAVs) relying on Vision-Based Navigation (VBN) in high-altitude, mountainous terrain face severe challenges due to geometric distortions in aerial imagery.

Surface Change Detection on Venus: An Inter‐Mission Comparison Framework Between Magellan and Future Radar Images

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Detecting surface changes on Venus by comparing Magellan synthetic aperture radar (SAR) data with future high‐resolution data from Envision and VERITAS will be essential for constraining present‐day volcanism and characterizing planetary surface processes.

Orthorectification of Bridges from High Resolution Satellite Images [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
High-resolution satellite imagery requires high-resolution height reference data to create orthorectified images. High-precision digital surface data and LiDAR data are expensive to acquire quickly and accurately.

Beyond the panacea narrative: Evaluating the capabilities and limitations of remote sensing for biodiversity net gain in England

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Five priorities for integrating remote sensing into biodiversity net gain in England, highlighting the need for transparent, validated, and interpretable approaches that complement, rather than replace, ecological field surveys. Abstract In England, biodiversity net gain (BNG) is a relatively new mandatory approach applied to many development sites ...

Counting elephants from space: An analytic framework for wildlife abundance surveys in heterogeneous terrain using satellites and AI

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We determine the analytic framework for satellite surveying using AI, for species such as elephants in heterogeneous terrain such as savannahs. For the elephant hotspot of Botswana, we compare satellite surveying to traditional aerial surveying methods.

Differential sensitivity analysis for the orthorectification of small satellite images

, 2009
By using differential sensitivity analysis, horizontal and vertical accuracy of orthorectification of monoscopic images taken by small satellites without using Ground Control Points (GCP) is predicted.

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring

River Research and Applications, Volume 42, Issue 6, Page 1223-1238, July 2026.
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...
