Application of ADAtools tools for InSAR based ground displacement map analysis: the coast of Granada

Satellite interferometry (InSAR) has become a consolidated technique for ground displacement detection and monitoring in the last years. InSAR based techniques allow to process large areas, providing numerous displacement measurements at low cost. This consolidation is confirmed by the emergence of regional, national, and European programs to monitor ground displacements using InSAR data. However, the interpretation of the outputs provided by such techniques is sometimes difficult and time-consuming. This is particularly critical for users who are not familiar with radar data. In this context, the development of tools and methods to automatize the retrieval of key information and to ease the interpretation of the results is needed to improve its operational use. A series of tools developed in the framework of different projects (MOMIT, SAFETY, U-Geohaz) is presented and an example of use in the project RISKCOAST is shown. The ADA (Active Displacement Areas) tools have been developed with the aim of easing the management, use and interpretation of InSAR based results. Specifically, the ADAFinder tool allows a semi-automatic extraction of the most significant Active Displacement Areas (ADas) detected by the InSAR analysis. We show its application to one of the test sites of the project Riskcoast, the coast of Granada. These tools have been developed to improve the exploitation capabilities of the European Ground Motion Service (EU-GMS), which will provide consistent, regular, and reliable information on natural and anthropogenic ground motion phenomena all over Europe. © 2022, National Technical University of Athens.
