Abstract
Abstract. SAFETY is a two-years European project started the 1st January 2016 and ended the 1st January 2018. The general aim of the project was to develop a methodology and tools in order to exploit Sentinel-1 data for detecting and monitoring the activity state of geohazards (e.g. landslides, volcanic and subsidence) and evaluating their impact on built-up areas and infrastructure networks, at a regional scale. The products of the methodology must support Civil Protection Authorities (CPA) in the risk management activities at a regional scale. In this contest, a strong effort has been spent to generate products that must be operative: reliable and easily to read by users who are not familiar with radar data. The developed procedure is fast, periodically repeatable, and case-adaptable. The methodology, allows the full exploitation of Sentinel-1 constellation data (wide area coverage, high temporal repeatability, freely available data) making feasible long term monitoring plannings. Moreover a free software tool for the Sentinel-1 SAR data processing has been developed. This work presents the developed methodology, through some images of the most significant results obtained over the two test sites of the project (the Canary Island, in Spain, and the Volterra municipality, in Italy), and explains both the strengths and the main lessons learnt for the future steps.
Highlights
1.1 The Safety ProjectSafety is a two years project, funded under the 2015 ECHO (European Commission’s Humanitarian aid and Civil Protection department) call “Prevention and preparedness projects in Civil Protection and marine pollution”, which started the 1st of January 2016 (Monserrat et al.,2017)
The aim of the project was to implement a methodology and develop tools in order to allow the use of the Persistent Scatterer Interferometry (PSI) technique as a constant input in the regional scale geohazard monitoring and management
The developed methodology simplifies the use of the PSI products by extracting the most significant detected Active Deformation Areas (ADA) and resuming the relevant information
Summary
1.1 The Safety ProjectSafety is a two years project (safety.cttc.es), funded under the 2015 ECHO (European Commission’s Humanitarian aid and Civil Protection department) call “Prevention and preparedness projects in Civil Protection and marine pollution”, which started the 1st of January 2016 (Monserrat et al.,2017). The aim of Safety was to improve the exploitation of Sentinel-1 data for the geohazads monitoring and the Civil Protection Authorities’ (CPA) activities of risk management, at a regional scale. This global goal has been achieved by: a) developing a simple and semi-automatic methodology to produce regionalscale maps of geo-hazards activity and urban impact; b) implementing a new open source software tool. The number of information is huge and not feasible to be used in an easy and fast way
