AI4Copernicus – Sentinel-1 GRD Pre-processing (Security Bootstrapping services)
The Security Bootstrapping services and resources have been developed in order to support the AI4Copernicus project’s open calls by reducing the time and resources of the bidders in the data preparation and allowing them to focus on the development of innovative services based on AI. This pipeline processes a S1 GRD product in native format to generate a terrain corrected image representing the calibrated backscatter in GeoTiff format
The Sentinel-1 GRD Pre-processing resource is available as a dockerized application. It is one of the Security Bootstrapping Services developed in AI4Copernicus.
The input of this pipeline is a Level-1 Ground Range Detected (GRD) product in its native SENTINEL-SAFE format (zipped or unzipped product), supporting SM and IW acquisition modes.
The output is a GeoTiff (by default) terrain-corrected image with one float32 band representing the calibrated backscatter (sigma0, gamma0 or beta0 depending on the selected parameters).
Several parameters are exposed to the users (e.g. final resolution, polarization and projection). Where possible, a standard value has been set, to facilitate the use by the less-expert users.
