The availability of high-resolution satellite imagery could help human rights groups by allowing them to survey scenes of heinous crimes without endangering the lives of researchers. With the help of satellite imagery, analysts could substantiate or refute news reports of systematic destruction of villages. While it would be dangerous for a non-governmental organization (NGO) to fly a spy plane over warring territories to look for mass graves, very high-resolution commercial satellite imagery could, without risk, provide data to much the same effect.
