Given the use of proprietary tools, the implemented processing pipeline cannot be openly released to the public. However, all processing steps can be accessed and reproduced as follows: The pre-processing of the Sentinel-1 imagery can be replicated with the open source ESA SNAP Toolbox 8.0 and the processing steps described in Fig. 2. The code of the HED-Unet based on Pytorch (v1.7) is available at https://github.com/khdlr/HED-UNet and the final post-processing script (Python v3.7) is available at https://download.geoservice.dlr.de/icelines/files/icelines_auxiliary_v1.zip. Additionally, this folder includes data used for the accuracy assessment, a Python script for bulk download (bulk-download-icelines.py) and an exemplary script (‘display-icelines-gee.js’) to display IceLines data with the corresponding Sentinel-1 scenes in Google Earth Engine.",
