As a UNESCO World Heritage website, Bagan in Myanmar is house to more than 2, 200 structures, consisting of pagodas and temples built from the 10 th to the 14 th centuries.

However, its age, integrated with the surface area subsidence and earthquakes over the area have actually postured excellent dangers to the stability of the historical monoliths and renowned pagodas at the large website. Therefore, the tracking of landscape surface area subsidence and vulnerability of the monoliths is essential to the defense and sustainable management of the Bagan heritage website.

A research study group led by Prof. Chen Fulong from the International Research Center of Big Data for Sustainable Development Goals (CBAS) and the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) has actually determined numerous hotspots and pagodas with displacement abnormalities connected to land cover modification and previous earthquakes by utilizing Interferometric Synthetic Aperture Radar (InSAR) techniques.

The research study was released in the International Journal of Digital Earth

InSAR is a strategy for mapping ground contortion utilizing radar pictures of the Earth’s surface area gathered from orbiting satellites. The noninvasive innovation is an effective tool to evaluate the vulnerability over the important heritage structures.

The group used high-resolution TerraSAR-X images gotten from 2019–2020 for contortion tracking based upon the little standard subset and consistent scatterer InSAR techniques.

The mix of the 2 multi-temporal SAR interferometry techniques pleases the two-scale tracking requirements from landscapes to monoliths, especially for massive world heritage websites.

” The non-contact tracking approach has prospective when standard techniques utilizing field ease of access and security are constrained,” stated Prof. Chen.
