Documenting violations of international humanitarian law from space: a critical review of geospatial analysis of satellite imagery during armed conflicts in Gaza (2009), Georgia (2008), and Sri Lanka (2009)

Published online by Cambridge University Press:  24 June 2013

Abstract

Since the launch of the first commercial very high resolution satellite sensor in 1999 there has been a growing awareness and application of space technology for the remote identification of potential violations of human rights and international humanitarian law. As examined in the three cases of armed conflict in Gaza, Georgia, and Sri Lanka, analysis of satellite imagery was able to provide investigators with independent, verifiable, and compelling evidence of serious violations of international humanitarian law. Also examined are the important limitations to such imagery-based analysis, including the larger technical, analytical, and political challenges facing the humanitarian and human rights community for conducting satellite-based analysis in the future.

Figures for building damages were all based on final post-conflict images recorded on 19 August 2008. Based on the fact that continued active fires in the villages were detected on 22 August 2008, it is likely that there were more than 300 damaged buildings in the four ethnic Georgian villages to the east of Tskhinvali (from Pirsi to Eerie).

29 Based on the imagery recorded on 19 August, multiple concentrations of Russian main battle tanks and assorted heavy transport vehicles were identified in villages north of Tskhinvali at the time arson attacks were occurring, strongly suggesting that Russian forces had passively supported the Ossetian campaign of looting and destruction against ethnic Georgian villages and property.

52 It is unlikely that either of these public facilities was functioning at the time; however, the school was later demolished and as of late 2010 there were no indications that the hospital had been reconstructed.

53 This explosion was detected by the same fire-monitoring sensors used during the Georgian conflict (2008).

54 SAR sensors are especially well suited for monitoring vessel traffic on open bodies of water, which would be of specific value to detailed studies on potential human-trafficking routes, as well as large-scale forced population displacements by boat.

56 The German SAR sensor TerraSAR-X is subject to the Satellite Data Security Act (SatDSiG) of 2007, which restricts civilian access to radar data collected over designated sensitive areas. It is not known at the time of writing to what extent in practice this policy has actually restricted data access over conflict zones.

58 The only information collected in relation to potentially unlawful acts in Gaza by Hamas was the identification and analysis by UNOSAT of damage to the retaining wall of a sewage treatment plant that resulted in a massive outflow event over 1.2 km long. The Goldstone Report assumed Israeli forces had been responsible; however, there were no eyewitnesses and little physical evidence. The Israeli government reviewed the case and concluded that although they could not rule out an accidental air strike, they thought it could have been committed by Hamas as part of a defensive plan to hamper the movement of IDF tank forces in the area. If this were the case then it would potentially represent a violation of customary international law as reflected in Article 56 of Protocol I and Article 15 of Protocol II, prohibiting the destruction of installations containing dangerous forces.

60 The 2004 US Senate report on US pre-war intelligence on Iraq indicated that when imagery analysts came to strongly divergent opinions about the significance of vehicle activity at the Amiriyah Serum and Vaccine Institute, there was no mechanism or review process to resolve the conflict, allowing the erroneous interpretation of ‘unusual’ activity to go into the Powel presentation. Further, it appears that imagery analysts may have shaped their findings on the locations of alleged mobile biological weapons (BW) agent production units to conform to fabricated reports by the informant ‘Curve Ball’. See ‘Report on the US Intelligence Community's Prewar Intelligence Assessments on Iraq’, US Senate, 7 July 2004, pp. 244–256, available at: http://web.mit.edu/simsong/www/iraqreport2-textunder.pdf (last visited June 2012).

61 A clearly associated risk with the proliferation of satellite imagery use by the humanitarian and NGO community is that groups may release products out of inexperience, excitement, or pressure to confirm preconceived expectations that do not necessarily account for this uncertainty or fully communicate it to end users, risking a typical rush to judgement error, as exemplified by the presentation of satellite imagery interpretations by then US Secretary of State Colin Powell at the UN Security Council in February 2003.
