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.

ZWDX: a global zenith wet delay forecasting model using XGBoost

Earth, Planets and Space
Tropospheric delays play a crucial role for Global Navigation Satellite Systems (GNSS). They are a major error source in GNSS positioning and, at the same time, also a variable of interest in GNSS meteorology.

Survey on differential estimators for 3d point clouds

Computer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

AN EVALUATION OF FEATURE LEARNING METHODS FOR HIGH RESOLUTION IMAGE CLASSIFICATION [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Automatic image classification is one of the fundamental problems of remote sensing research. The classification problem is even more challenging in high-resolution images of urban areas, where the objects are small and heterogeneous.

Fine‐Tuning a Weather Foundation Model With Lightweight Decoders for Unseen Physical Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Recent advances in AI weather forecasting have led to the emergence of so‐called “foundation models”, typically defined by expensive pretraining and minimal fine‐tuning for downstream tasks. However, in the natural sciences, a desirable foundation model should also encode meaningful statistical relationships between the underlying physical ...

Determination of the Sample Size of Linear Features Used in Cartographic Quality Control Through Monte Carlo Simulation

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT In sampling‐based process, sample size is always a debated topic. To assess positional accuracy using points, there are several studies and standards that determine what sample size should be used. However, for positional control using lines, there is no knowledge of a study that indicates the sample size.

Three Decades of Glacial Changes on the Western Antarctic Peninsula Revealed by Historical Aerial and High‐Resolution Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Antarctic Peninsula has been climate‐sensitive since the mid‐20th century, but long‐term glacier mass balance data are scarce. This study uses historical aerial and high‐resolution satellite imagery to estimate mass changes on the western Antarctic Peninsula (66°S $66{}^{\circ}\mathrm{S}$–68°S $68{}^{\circ}\mathrm{S}$) from 1989 to 2020 ...
