The Syria Conflict Mapping Project (screenshot above), a project of the Carter Center, has been documenting events in the Syrian civil war since 2012 using open source information. “Using these publicly available resources, as well as regular consultations with stakeholders in the country, the Center has documented and mapped over 40,000 conflict events in Syria (including clashes, aerial bombardments, artillery shelling, etc.), the changing relations between thousands of armed groups, movements of internally displaced people, and humanitarian conditions.” [via]
