PROTHEGO (PROTection of European Cultural HEritage from GeO-hazards) is a collaborative research project funded in 2015–2018 in the framework of the Joint Programming Initiative on Cultural Heritage and Global Change (JPI-CH) – Heritage Plus. The project aims to make an innovative contribution towards the analysis of geohazards in areas of cultural heritage, and uses novel space technology based on Interferometric Synthetic Aperture Radar (InSAR) to retrieve information on ground stability and motion in the UNESCO World Heritage List (WHL) monuments and sites of Europe. This report introduces PROTHEGO’s Work Package (WP) 2: Harmonisation of available PS data, and creation of digital factsheets, led by the Natural Environment Research Council (NERC) – British Geological Survey (BGS) and aimed to define, catalogue and assess the availability of satellite-derived ground motion information from multi-temporal InSAR and Persistent Scatterers (PS) techniques for the UNESCO WHL sites of Europe. WP2 consists of two main tasks: 2.1 – Analysis of satellite InSAR and PS datasets available at European scale; and 2.2 – Harmonisation of InSAR and PS ground motion information and creation of digital factsheets. Their goal is to generate a GIS catalogue of the available satellite InSAR data for the UNESCO WHL sites of Europe, and digital factsheets summarising the observed ground motion velocities and deformation histories of the PS reflectors within each WHL site, alongside two technical reports. This is the first report describing the methodology adopted for, and results obtained from, the analysis of the availability of ground motion information for the WHL sites of Europe (i.e. Task 2.1). This information is based on InSAR processing of satellite radar imagery that was carried out in the framework of ongoing or recent European, national and/or research projects (such as ESA-GMES Terrafirma, and the Italian Extraordinary Plan of Environmental Remote Sensing EPRS-E), as well as those available through published literature (e.g., scientific papers, project reports). Information on data availability for the WHL sites was recorded in an ad hoc catalogue, together with metadata on the retrieved ground stability and motion datasets (e.g., data source, satellite and sensor, monitoring period, acquisition mode). The analysis allowed the delineation of a general overview of the coverage of InSAR datasets for the UNESCO sites at European scale, as well as the identification of data coverage gaps. The results reveal that, as of the end of 2016, 147 sites (i.e. 37% of the analysed 399 sites of PROTHEGO) are covered by existing datasets and/or published literature, whereas there is a data coverage gap for 252 sites (i.e. 63%). Therefore InSAR information can or may be accessible to study geohazards in more than one-third of the total European UNESCO sites. It is to be noted, however, that in addition to the datasets and literature found so far, many other unpublished studies may exist, as well as other digital datasets that could be made available to PROTHEGO via other projects, suggesting that even more sites than the 37% figure provided in this report may be already covered.
