Sobloo Sentinel-1 L1 SLC (SAFE)
Sobloo Sentinel-1 L1 SLC (SAFE)¶
Sentinel-1 L1 SLC (SAFE) provides full scenes of Sentinel-1 (A/B)'s C-band synthetic aperture radar sensor in processing level L-1C Single Look Complex (SLC) in SAFE folder structure.
In the example, the workflow, the area of interest and the workflow parameters are defined. After running the job, the results are downloaded and visualized. For more information, refer to the block's UP42 Marketplace page and Documentation.

In the above code cell, we added the basic input parameters. However, the block accepts additional parameters as per workflow.get_parameters_info(). You can add the parameters to our parameter configuration in the following steps:
In [7]:
input_parameters["sobloo-s1-slc-fullscene:1"].update({"mission_code": None,
"orbit_direction": None,
"acquisition_mode": None,
"orbit_relative_number": None})
# Check if everything is as expected
