Urban growth is increasingly shifting from horizontal expansion to vertical development, resulting in skylines dominated by high-rise buildings. The post-construction operations and maintenance of these buildings are critical, requiring regular structural health monitoring (SHM) proactively identify address potential safety concerns. Interferometric synthetic aperture radar (InSAR) has proven effective for building safety, but most studies rely on high-resolution (SAR) images. high cost limited coverage images restrict their use large-scale monitoring. Sentinel-1 medium-resolution SAR images, which freely available offer broad coverage, make SHM more feasible. However, the monitoring, especially at large spatial scales, remain limited. To this gap, study, PS-InSAR technology proposed performing a comprehensive assessment super Guangzhou–Foshan Metropolitan Area (GFMA) analyzing influencing factors. Our shows that while overall satisfactory, certain areas, including Pearl River New Town, central Huadu district Guangzhou, southeastern Shunde Foshan, exhibit suboptimal conditions. We verified findings using GNSS data on-site investigations, confirming imagery offers reliable accuracy health. Furthermore, we identified factors such as settlement soft soil layers, construction surrounding (underground) infrastructure, aging, could potentially impact safety. results demonstrate provide reliable, rapid, cost-effective method stability, enhancing our understanding underlying mechanisms informing strategies prevent crises, also ensuring sustainable development society.
