Online Training courses
We offer entire curriculum, materials, and courses that allow you to engage with training on your own time.
Training together is the key to our success. The more you are empowered to leverage InSAR and EO59 systems the higher we will reach, and we are already 2000km in the sky.
In Person Training
Nothing beats collaborating and finding a way through some of the toughest challenges of InSAR together.
SarProZ
Systems Training
An advanced two weeks long series of virtual sessions focusing on SAR and SAR interferometry.
At the conclusion of which you will be able to operate SarProZ to develop and process your own data.
Ground subsidence in Shanghai as analyzed by RASER using Cosmo data and the Sarproz software. Blue indicates stable terrain. Yellow color highlights ground compaction. Yellow strips reveal tunnels excavated under the ground for building subway lines (which caused a localized ground subsidence of the terrain above the tunnels).
The Sarproz-based training course on Synthetic Aperture Radar (SAR), SAR interferometry (InSAR) and Advanced Differential SAR Interferometry (A-DInSAR). The course has been designed to teach the basic concepts behind SAR and InSAR and at the same time to train the participants to reading, processing and understanding SAR/InSAR/A-DInSAR data.
The course will comprise theoretical lectures and tutorials. The whole course will be held online and the tutorials will be based on the use of the Sarproz software together with real data acquired over various areas in the world by most of the existing satellites (Sentinel-1, TerraSAR-X, COSMO-SkyMed, ALOS, Envisat and more).
The program presents for each day a topic treated both in the theoretical aspects and with practical exercises. Each topic is designed to learn particular objectives. Application examples are listed as well to give an idea about the usefulness of each topic. The course will be held online, for a total of 10 days (theory and practice) according to the following structure (more details later in the document):
The SARPROZ software. SARPROZ has a Graphic User Interface allowing anybody using it, even with basic technical knowledge and understanding. At the same time, SARPROZ offers a wide range of options for advanced users, resulting in the best available tool for SAR/InSAR data processing.
1. Basic Module (SAR principles and DInSAR) – Week 1 (Monday-Friday)
2. Advanced Module (Multi-image Advanced DInSAR/A-DInSAR) – Week 2 (Monday-Friday)
Tutorials will be taught using the software Sarproz. Trainees will process real data acquired by various satellites over different areas in the world.
One Sarproz license will be provided for each participant for the whole course duration plus an additional month after the end of the course, to allow the trainees to keep practicing. Students will need to install the software on their own computers to perform the exercises on real data during the course. Sample data will be distributed as well.

The signal has a sudden drop at the beginning of 2010, when the building collapsed. The lower time series shows that, before collapsing, the building had an acceleration, highlighting that the building was affected by stability problems (data processed by Sarproz).
