This past weekend, the Washington Post ran an article describing how human rights groups are documenting atrocities by using satellite imagery:
The catalyst is a partnership between Amnesty and the American Association for the Advancement of Science (AAAS) that’s pioneering a new kind of human rights observation: the use of high-resolution satellite imagery—commercially available only since 2001—to document atrocities in areas made inaccessible to watchdog groups. The unusual collaboration started about a year ago, with test projects looking at Zimbabwe and Lebanon. The Darfur effort is by far their biggest yet, and the most politically significant.
Sample imagery is here if you desire to see before/after images of burned out villages.
