Abstract text The project entitled ‘’SpaCeborne SAR Interferometry as a Noninvasive tool to assess the vulnerability over Cultural hEritage sites (SCIENCE)’’ introduce the InSAR techniques to cultural heritage sites protection.
The four cultural heritage sites that are examined are: a) the Acropolis of Athens and b) the Heraklion City Walls in Crete (Greece) and c) the Ming Dynasty City Walls in Nanjing and d) Great Wall in Hebei and Beijing (China).
In the framework of SCIENCE project, the state-of-the-art techniques of multitemporal Synthetic Aperture Radar Interferometry (MT-InSAR) are applied for the detection of ground deformation in time and space. These remote sensing techniques are capable to measure deformation’s impact with millimetric accuracy. The MT-InSAR techniques that are used are: the Persistent Scatterers Interferometry (PSI), the Distributed Scatterers Interferometry (DSI) and the Tomography-base Persistent Scatterers Interferometry (Tomo-PSInSAR). Supplementary to the radar data, is used high-resolution optical data is used for the identification of the persistent scatterers.
The main datasets that are used are: a) open access ERS-1 & 2 and Envisat SAR datasets, Copernicus SAR datasets (Sentinel-1A & B) and third part mission high resolution SAR datasets (TerraSAR-X Spotlight and Cosmo-SkyMed), b) the optical datasets of Pleiades 1A and Pleiades 1B (with spatial resolution up to 0.5m), GF-2 (with spatial resolution up to 0.8m) and Senitnel-2 (with spatial resolution up to 10m).
Moreover, the validation of the interferometric results is taking place through a) in-situ measurements in terms of geological and geotechnical framework and b) data associated with the cultural heritage sites’ structural health.
In addition, SCIENCE project is a result of the bilateral cooperation between the Greek delegation of Harokopio University of Athens, the National Technical University of Athens, the Terraspatium S.A., the Ephorate of Antiquities of Heraklion (Crete), the Acropolis Restoration Service (Athens) of Ministry of Culture and Sports and the Chinese delegation of Science Academy of China (Institute of Remote Sensing and Digital Earth) and the International Centre on Space Technologies for Natural and Cultural Heritage (HIST) under the auspices of UNESCO (HIST-UNESCO).
Concluding, SCIENCE introduces the creation of a validated pre-operation non-invasive system and service for risk assessment analysis of cultural heritage sites including their surrounding areas. Such a service could be very beneficial for institutions, organizations, stakeholders and private agencies that operate on the cultural heritage protection domain.
