Satellite Testimony
A Forensic Methodology for Data-Silent Environments
Overview
Every environmental crime leaves two traces. The first is physical — detectable in satellite imagery, atmospheric sensors, and chemical signatures in soil and water. The second is human — carried in the bodies, memories, and voices of communities who witnessed it. Institutional systems routinely record neither.
Satellite Testimony is a forensic methodology that brings these two traces together. By pairing longitudinal satellite imagery analysis with structured oral testimony from affected communities through a correspondence protocol designed to meet legal admissibility standards, the methodology produces a new form of environmental evidence that neither technology nor human witness can generate alone.
The Problem
The communities most affected by industrial environmental harm are also the communities least equipped to prove it. Their testimony doesn't meet regulatory evidentiary standards. Their observations conflict with official monitoring records. And satellite imagery — while powerful — lacks the human context that makes environmental harm legible to courts, policymakers, and journalists.
The gap between what communities know and what institutions can receive is not a technical problem. It is a design problem. Satellite Testimony bridges that gap — not by fighting the evidentiary hierarchy, but by working within it.
The Methodology
Three layers linked by a correspondence protocol:
Satellite Archive Analysis
Longitudinal imagery from Planet Labs and Sentinel-2 analysed for a multi-year period, documenting environmental change: vegetation loss, water quality degradation, land use change, atmospheric signatures, and industrial discharge patterns.
Community Testimony Collection
Structured oral testimony collected through a consent-based, culturally sensitive documentation process. Testimony georeferenced to specific locations and time periods. Participants retain full control over how their testimony is stored and shared. All participation voluntary with full withdrawal rights.
Correspondence Protocol
Satellite observations and community testimony linked to identify where the two evidence layers corroborate each other, where they diverge, and where both diverge from the official record. Designed to meet international legal admissibility standards.
Every evidence package is SHA-signed and chain-of-custody authenticated — usable in courts, regulatory proceedings, and investigative journalism.
Why It Matters
Satellite imagery is already used in legal proceedings — by the ICC, ICJ, and international human rights tribunals. Community oral testimony is already used in legal proceedings. What does not yet exist is a systematic methodology for producing them together as a single authenticated evidence package.
Satellite Testimony fills that gap. It is a correspondence methodology — making two epistemologically different forms of knowledge speak to each other in a format that courts, regulators, and journalists can act on.
Fieldwork
Satellite Testimony has been developed through eighteen months of forensic fieldwork in Turkey's Sakarya River Basin. The Sakarya pilot has produced documented satellite imagery archives, established community relationships, and a tested consent and testimony protocol. Three complete evidence packages are in production.
The methodology is designed to be replicable. The open-source toolkit — currently in development — will enable community researchers in other data-silent environments to implement Satellite Testimony independently.
Status
Operational. Sakarya Basin pilot active. Open-source toolkit in development. Three evidence packages in production.
