ADATools: free and easy-to-use tools for semi-automatically extracting and analysing multitemporal interferometric displacement maps

Abstract. The availability of displacement maps based on Multi-Temporal Satellite SAR Interferometry (MT-InSAR) has greatly increased, particularly since the launch of the Copernicus Sentinel-1 satellites in 2014. These satellites provide open and free data, leading to services like the European Ground Motion Service (EGMS) which offers highly detailed displacement maps across Europe. Despite their potential for territorial management and risk assessment, the use of these maps is limited due to the complexity of the data and the lack of experience in interpreting MT-InSAR results. Projects such as RASTOOL and SARAI aim to address this by developing automated tools that simplify and expedite the analysis of EGMS data. The ADATools suite, including ADAFinder, ADAClassifier, and ADAImpact, automates the identification, classification, and impact assessment of active deformation areas (ADAs). These tools facilitate the use of displacement data for non-experts, supporting better management of territorial and infrastructural risks. Examples of ADATools applications to EGMS data highlight their strengths and future development potential, as part of the SARAI project.
