SARCalNet (https://www.sarcalnet.org)
This GitHub Organization hosts SARCalNet related projects and resources.
To respond to the need of standardized cal/val practices and of a curated network of reference data, the SARCalNet initiative was created within the CEOS WGCV SAR subgroup.
The SARCalNet initiative aims to establish and curate the SARCalNet database, which will allow for the consistent dissemination of reliable and standardized information about SAR calibration sites and targets.
The initiative also aims at the documentation of requirements for calibration targets and image analysis, which shall be provided to the broader SAR community through the SARCalNet library. Those, together with the calibration sites database, sample datasets and tools shall facilitate the harmonized use of multiple calibration sites and promote cross-validation between different SAR systems.
