In the context of space-borne geodetic techniques, Differential Synthetic Aperture Radar Interferometry (DInSAR) has demonstrated its efficacy in measuring surface displacements in different conditions and deformation scenarios. In particular, the advanced DInSAR method referred to as Parallel Small BAseline Subset (P-SBAS), developed by IREA-CNR, has emerged as particularly suitable to effectively and efficiently investigate the temporal evolution of surface displacements both in natural and anthropogenic hazard contexts. We refer to volcanoes, earthquakes, landslides, or human-induced deformation like subsidence from fluid exploitation, mining activities, and the construction of large infrastructures.

The P-SBAS algorithm has been released as an on-demand web-based tool by integrating it within the EarthConsole® platform and currently contributes to the on-demand remote sensing component of the EPOSAR service. In particular, EarthConsole® is a cloud-based platform supporting the scientific community with the development, testing, and hosting of their processing applications to enable Earth observation data exploitation and processing services. Nevertheless, the P-SBAS processing capability is still available through EPOSAR, the processing service developed by IREA-CNR, also accessible in the framework of the European Plate Observing System (EPOS) Satellite community, that provides systematic ground displacement products of several areas on Earth.

The herein presented on-demand P-SBAS tool enlarges the EPOSAR service portfolio and empowers users to seamlessly generate surface displacement maps and time series exploiting C-band satellite data. In particular the P-SBAS service allows the scientific users to process both Sentinel-1 and ENVISAT SAR images in fully autonomous manner, through a user-friendly web graphical interface which permits them to follow the progress of the processing tasks and avoids the need of data download on their own processing and archiving facilities.

The presented on-demand P-SBAS/EarthConsole® processing service will be accessible for the scientific community through the Network of Resources (NoR). In particular, the NoR is an ESA initiative that, among several missions, sponsors the scientific users to exploit commercial platform resources and services in the Earth Observation field, like EarthConsole®.

The training course has been designed to be a hands-on session structured in three main modules:

1. Overview on the Advanced DInSAR technique with a focus on the P-SBAS algorithm for obtaining displacement time series and corresponding mean deformation velocity maps;

2. Introduction to the EarthConsole® platform and its processing environment;

3. Presentation of the on-demand P-SBAS/EarthConsole® service for C-band satellite data interferometric processing focused on the Sentinel-1 platform, with also a brief overview on the ENVISAT one.
