Crowdsourcing Maps of ISIS and Other Middle East Conflicts

Thomas van Linge recently tweeted a photo of a munitions truck being blown up in Syria, presumably by the First Coastal Division, a faction of rebels affiliated with the Free Syrian Army. In his tweet, which was sent to his more than 13,000 followers, van Linge linked to a YouTube video of the explosion, and included its location: “near Joureen, Ghab plain.” He then cross-referenced the location with a home-made map to make sure he had the most up-to-date movements of the Syrian rebels.
