A comparative case study of MTInSAR approaches for deformation monitoring of the cultural landscape of the Shanhaiguan section of the Great Wall

A comparative analysis of two MTInSAR techniques, PSInSAR and SBAS, reveals the structural stability of the Shanhaiguan section of the Great Wall while identifying localized deformation risks. Using high-resolution TerraSAR-X data from 2015–2017, researchers found that while the site remained largely stable, rock falls in mountainous areas posed potential hazards. The study highlights the need for more adaptable MTInSAR methods to effectively monitor linear heritage structures like the Great Wall, offering valuable insights for conservation efforts.
