Abstract text For more than 20 years, the Centre Spatial de Liège (CSL) has developed Synthetic Aperture Radar software solutions in a suite called CIS (CSL InSAR Suite). CIS is a command-line software written in C, dedicated to the processing of synthetic aperture radar data, allowing the production of analysis-ready outputs such as displacement maps, flood extend, or fire monitoring. Advanced methods are also included, making CIS distinct from other competing SAR suites.

With more than 500 000 registered users, the open-access SentiNel Application Platform - SNAP, developed since 2015 by Brockmann Consult (Hamburg, Germany), has become the standard tool for processing remote sensing data. It was originally tailored to Sentinel 1-3 images, but now accommodates data from most common satellite images, including non-ESA missions (e.g., ICEYE, NOVASAR). The largest part of SNAP users belongs to the radar (Sentinel-1) community. SNAP integrates classical operators of remote sensing, including data reading, co-registration, calibration, raster algebra, and so on. A major particularity of practical and strategical interest is that SNAP is available is golden-open-access, allowing to access directly to the core codes and modify it. Moreover, SNAP supports the inclusion of plugins with a cookbook to developers.

This abstract reports the work of progressive inclusion of the CIS software modules into the SNAP open-source software, as plugins. To fulfill this objective, we are using the Standalone Tool Adapter of SNAP to include external command-line functionalities. The objective of the tool adapter is to create the paths that will link the external application to the SNAP software. We started the migration using a series of simple to complex tasks in different programming languages (C/C++, Python, and Matlab).

CIS plugins in SNAP will be accessible from a new dedicated menu in the user interface. Currently, we integrated the coherence tracking and multiple aperture interferometry to the SNAP software. Additional tools will be included in future developments.

During the event, a presentation of the different tools will be performed. Interested scientists are invited to contact directly the authors to request help with the installation of the plugin at the session.
