Satellite imagery has become an increasingly valuable tool in judicial proceedings, serving as critical evidence in cases related to human rights violations, environmental degradation, migration tracking, disaster response, and corruption investigations. These images provide verifiable and objective data that can support legal claims, investigations, and court decisions.

Satellite imagery provides a unique vantage point that enables investigators, lawyers and judges to document and verify events in remote, dangerous or otherwise inaccessible locations. This capability is particularly important in international criminal cases where ground-based evidence may be limited or unreliable.
The Growing Adoption of Satellite Evidence in Courts
Despite being a relatively new form of evidence, satellite imagery is increasingly accepted in legal proceedings. The international criminal justice system - including judges, lawyers, and prosecutors - has begun integrating geospatial evidence into their casework.
Advantages of Satellite Imagery as Legal Evidence:
Objective and Reliable: Provides timestamped, geolocated proof that cannot be easily manipulated.
Long-Term Monitoring: Tracks events over months or years, identifying changes that may be imperceptible on the ground.
Corroborative Value: Supports witness testimonies, digital evidence, and on-the-ground investigations.

Applications of Geospatial Technologies in Human Rights Investigations
One of the most notable applications of geospatial technologies in human rights documentation is satellite imagery analysis. This technology has been used in various conflict zones and crisis areas to provide compelling evidence of human rights abuses.
Examples include:
Lebanon: High-resolution satellite images have been used to illustrate the scale of destruction. Images taken in November and December 2024 reveal damage that may otherwise go unnoticed.
Los Angeles: Satellite imagery has effectively captured the scale and intensity of wildfires, providing clear visuals of destroyed homes, businesses, and infrastructure. High-resolution images objectively present the extent of the fires.
Gaza: Satellite imagery has been crucial in assessing the extent of destruction in the Gaza Strip. Experts have used high-resolution Earth observation technologies to monitor and analyze damage over large areas, offering an accurate and unbiased perspective.
Poland: Satellite data has been used to document flood-affected areas. The extent of flooding has significantly exceeded initial estimates, highlighting the importance of these data for effective crisis management.
Darfur, Sudan: Analysts have used satellite imagery to investigate the burning of villages, providing crucial evidence of war crimes.
Sri Lanka: Remote sensing has been instrumental in documenting shelling in civilian-designated areas, shedding light on potential violations of international humanitarian law.
Nigeria: Satellite data has been employed to assess the environmental impact of oil spills on local communities, holding corporations accountable for ecological destruction.
Syria and Iraq: Analysts have documented the destruction of cultural heritage sites, including mosques and ancient monuments, reinforcing legal claims of cultural rights violations.
Burkina Faso: used satellite imagery to locate and count the 95 vehicles destroyed in the attack, which stretched over five kilometres of highway.
The Role of Geospatial Evidence in International Courts
Geospatial evidence is increasingly being utilized by international legal institutions such as the International Criminal Court (ICC), the International Court of Justice (ICJ), and the International Criminal Tribunal for the Former Yugoslavia (ICTY). These courts recognize the importance of satellite imagery and geospatial data in meeting international legal standards for evidence collection.
The ICC Office of the Prosecutor (OTP) integrates Earth observation technologies to align with best practices outlined in Daubert standards, ensuring the reliability and admissibility of evidence. This technological approach enhances the quality of evidence required to substantiate claims of human rights violations beyond reasonable doubt.
Legal Standards and the Use of Satellite Imagery
In the United States, the Daubert Standard governs the admissibility of new scientific evidence, including satellite imagery analysis, in court. This standard has facilitated the use of satellite imagery in criminal cases by ensuring that expert testimony and scientific methods are both reliable and relevant. For example, in 2005, Arizona authorities used high-resolution IKONOS satellite images to prove that a Scottsdale land developer illegally cleared public and private land. By comparing satellite images taken before and after the alleged clearing, investigators identified discrepancies that confirmed the crime.
The Daubert Standard, or similar criteria, has been adopted by other countries and is occasionally referenced in international criminal cases to assess the admissibility of satellite data. In proceedings before the International Criminal Court (ICC), prosecutors frequently rely on satellite imagery to substantiate allegations of war crimes, crimes against humanity, and other violations. Such evidence is critical in documenting:
Destruction of property
Attacks on civilian infrastructure
Targeting of humanitarian and peacekeeping missions
Bombardment of non-military targets
Military infrastructure identification
Evidence of arson, roadblocks, and bomb craters
Large-scale human gatherings during conflicts
Conclusion
Geospatial technologies have revolutionized the way human rights violations are documented, providing critical evidence for international justice. By overcoming physical and political barriers, satellite imagery and remote sensing enhance transparency and accountability in human rights investigations. As legal institutions continue to embrace these technologies, they play an increasingly vital role in upholding justice and ensuring that perpetrators of human rights abuses are held accountable on the global stage. Legal professionals, investigators, and human rights organizations must leverage this technology to strengthen their cases and ensure justice is served.
