Post processing tools for wide area interferometric products

Convener: Lorenzo SolariECSECS | Co-conveners: Oriol Monserrat, Anna BarraECSECS

Satellite interferometry is now established as a reliable and precise technique to measure ground motion. Regions, nations and even continents have been or will be investigated thanks to the effectiveness of this technique. On one side, the availability of these data offers a great opportunity for the geoscience community to study known moving areas and discover new ground motion phenomena. On the other side, such data require proper interpretation; this process can be difficult and time consuming when dealing with millions/billions of measurement points.
This short course will introduce to a set of post-processing tools (ADA Tools) developed by the Geomatic Division of the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) to deal specifically with wide area interferometric products and ease the interpretation of the results. The package automatises methods and procedures classically performed in a geographical information system environment and it is composed of 4 modules which are accessible through a graphical user interface or through command line.
The first part of the course will introduce to wide area interferometric products and in particular to the data distributed by the Copernicus Land Monitoring Service in the framework of the European Ground Motion Service. A brief introduction to interferometry principles will be offered to those participants who are not familiar with the interferometric technique. This section will also provide the knowledge necessary to understand the content of an interferometric dataset and interpret the outputs of the post-processing tools.
The second part of the course will present the characteristics of ADA Tools and the graphical user interface. Participants will learn, through the analysis of real data, how to run the tools and modify properly input thresholds and parameters in different environmental contexts. Finally, a guided discussion on the results will allow participants to acquire the knowledge necessary to use the tools and their outputs in everyday activities.
Course material will include the software package and sample data. Participants will require (preferably but not mandatory) basic knowledge of radar satellite data analysis and interferometric data interpretation. The course targets researchers and stakeholders interested in ground motion measurements for a wide variety of activities, encompassing geohazard management, infrastructures monitoring and land planning.
