How Al Jazeera English Gathered Data to Map Syria's Rebellion
Posted: 7/19/2013  |  By: Sarah Marshall |
Al Jazeera English yesterday published an interactive that maps the Syria rebellion.

The interactive is based on data collected from 900 opposition fighter groups in the country, gathered though good old fashioned journalism. Al Jazeera English's Syria expert Basma Al Atassi made dozens of telephone calls to the groups on the ground, asking questions about the numbers of people involved in each group, where they are based, and noted other details.
