The GAMMA Software


The GAMMA Software is a commercial software developed and maintained by GAMMA. We are dedicated to keep the software at a very advanced level. Through our R&D projects and the many contacts to highly competent SAR/InSAR/PSI specialists, we get valuable inputs to the software development activities. We regularly implement new functionality and adaptations to support new sensors and algorithms. Software licenses are in use world-wide supporting researchers, companies and public authorities in their daily work.


The GAMMA software supports the entire processing chain from Synthetic Aperture Radar (SAR)  raw data to end products such as digital elevation models, displacement maps and land use maps. The GAMMA Software includes several Modules, each one consisting of documented, well structured code. The software is a toolbox providing a wide functionality to support the users in the setting up different processing tasks. Programs can be run individually on the command line or they can be called from scripts that permit running processing sequences in a more automated and efficient way.

The SAR image co-registration and geocoding functionality is also available as a separate GEO package. Furthermore, a special motion compensation package (MOCOM) and a Time Domain Back Projection processor (TDBP) are available for advanced processing of airborne data. Check here below for more technical details and news about updates.

Training courses


Following the increasing interest on the use of radar remote sensing data in bio- and geophysical applications,  GAMMA offers a wide range of training courses covering theoretical as well as practical aspects of SAR data processing, interferometric SAR processing, PS-InSAR  and related applications. Training in small groups is organised on a regular basis. They typically consist of an introduction to the topic of the course followed by practical processing examples using the GAMMA software modules. Ad-hoc courses can be arranged to serve specific needs or interests. Check the dates of the next training courses or This email address is being protected from spambots.
