Glacier Offset Tracking with the GAMMA software

• This collection of python scripts walks you through the processing of pairwise offsets for Sentinel-1 data.
• Data needs to be downloaded manually (from e.g ASF). Afterwards, however, the processing can be done using our scripts in the order they are numerated
• Some caution needs to be paid in the setup of the relative paths as most of them are still hardcoded (but all relative to the main script-directory)

How to proceed?

In order to follow the proposed approach, this flowchart might be a good starting-point:
