The Global Authentication Project consists of a wide community of open source researchers assisting in Bellingcat research through structured tasks and feedback. For this dataset, we are working with many individuals who have Ukrainian language skills and others with local contextual knowledge of the events and places seen on the map. Other participants include individuals skilled in geolocation and chronolocation, with all contributions being vetted by Bellingcat researchers.
The aim of this project is to detail incidents where there is open source evidence of potential civilian harm in Ukraine, as well as attempting to clarify where and when such events took place. Documenting these incidents is important given claims by the Russian government in particular that it is not seeking to attack civilians and avoid impacting civilian infrastructure.
