Differential settlements monitoring in railway transition zones using satellite‐based remote sensing techniques

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 27, Page 4824-4844, 14 November 2025.
Abstract Railway track transitions are prone to uneven settlements and track geometry degradation. Traditional monitoring methods are limited in coverage, which highlights the need for novel solutions. This study proposes a method that systematically integrates the high spatial resolution of Persistent Scatterer Interferometric Synthetic Aperture Radar
