This guide outlines the tools and techniques to establish a foundation for visual analysis and discusses how these techniques can assist in identifying notable landscape features pertaining to agriculture, settlements, water catchment, and livestock in northern Somalia. To the knowledge of the Signal Program analysts, there is no systematic open-source remote sensing documentation of frequently occurring natural and man-made features in Somalia. This guide helps users to identify and analyze these features, particularly humanitarian practitioners supporting activities in the Horn of Africa. This project, titled “Children on the Move: Using Satellite Data Analysis in Conflict/Famine-Affected Areas,” was carried out in collaboration with UNICEF, the GovLab at NYU, and the Signal Program on Human Security and Technology at Harvard Humanitarian Initiative.
This study explores how pastoralists respond to changing environments in Somaliland . An agent-based model is used to simulate the movement of nomadic pastoralists based on typologically diverse, historical data of environmental, interpersonal, and transactional variables in Somaliland and Puntland between 2008 and 2018. Through subsequent application of spatial analysis such as choropleth maps, kernel density mapping, and standard deviational ellipses, we characterize the resultant pastoralist population distribution in response to these variables.
This study is the first geospatial-based history of a conflict created primarily through a fusion of remote sensing and previously public event data. The researchers of the Signal Program spent many months cross-referencing and analyzing over 40,000 square kilometers of archival satellite imagery of Sudan with more than 2,000 published reports of incidents occurring between January 2011 and mid-2012.
Key findings of the study include evidence of the apparent intentional destruction of more than 2,000 civilian dwellings and other structures; the intentional targeting and destruction of four humanitarian facilities; identification of specific armed actors, units, and chains-of-command allegedly involved in specific attacks in Sudan; and evidence of the mass displacement of civilian populations.
This article documents the development and initial use case of the GRID (Ground Reporting through Imagery Delivery) methodology by the Harvard Humanitarian Initiative (HHI). GRID was created to support corroboration of witness testimony of mass atrocity related-events using satellite imagery analysis. A repeating analytic limitation of employing imagery for this purpose is that differences in the geographic knowledge of a witness and an imagery analyst can limit or impede corroboration.
The aim of this article is to highlight potential methods applicable to a standard forensic approach for the analysis of high-resolution satellite imagery that may contain evidence of alleged mass atrocities. The primary method employed is the retrospective analysis of a case study involving the use of high-resolution satellite imagery analysis to document alleged mass atrocities. The case study utilized herein is the Satellite Sentinel Project’s reporting on the May 2011 sacking of Abyei Town by Government of Sudan-aligned armed actors. In the brief case study, categories of objects, patterns of activities, and types of alleged mass atrocity events are applied the Abyei Town incident.
At the evolving frontier of modern humanitarianism, non-governmental organizations are using satellite technology to monitor mass atrocities. As a documentation tool, satellites have the potential to collect important real-time evidence for alleged war crimes and crimes against humanity. However, the field remains experimental and ill-defined, while useful court evidence cannot be produced without a standard methodology and code of ethics. In this paper, members of the groundbreaking Satellite Sentinel Project review the historical development of satellite documentation and some of its landmark projects, and propose necessary measures to advance the field forward.
The Georgetown Journal of International Affairs published an article authored by Signal Program staff in which they detail the technology, perceived impact and lessons learned from running operations for the Satellite Sentinel Project. This inside assessment of the Satellite Sentinel Project has been offered open source by the journal in order to inform humanitarian practitioners, scholars and the public.
Remote sensing can provide unique, sometimes otherwise unavailable, information about human rights violations occurring in non-permissive environments, over large geographic areas, and across long and multiple timeframes. The evidentiary potential of RS analysis currently appears not to be fully exploited by international criminal justice mechanisms. The purpose of this paper is (A) to illustrate the nature of RS analysis and its evidentiary potential and limitations, (B) to identify the key, repeating factors across regional and cultural contexts and types of crimes that influence its limited use in court, and (C) to explore steps and strategies for overcoming the challenges.
During armed conflict in East and Central Africa civilian dwellings are intentionally targeted and razed. These traditional civilian dwellings are known as tukuls which are primarily mud and thatch huts.
The intentional destruction of these dwellings, given their prevalence in these regions, is often one of the only available indicators of the intentional targeting of civilians observable in satellite imagery.
This field has lacked accepted methodologies for performing this type of analysis. This guide is the first to focus on tukuls because they are a uniquely valuable metric for both documenting attacks on civilians during armed conflicts and assessing potential mass displacement that can result from these incidents.
This guide is the second in a series of Satellite Imagery Interpretation Guides. Future satellite imagery interpretation guides from the Signal Program may focus on other, related phenomena and structures present in similar operational contexts.
Satellite Imagery Interpretation Guide: Displaced Population Camps is intended to help address the absence of public and standardized training resources for those seeking to use high resolution satellite imagery in support of refugee/IDP assistance operations. Students, general audiences, and volunteers studying and analyzing satellite imagery of displaced population camps may find this training resource beneficial.
The guide provides case studies of displaced population camps in East Africa and the Middle East. Dimensions, colors, shapes, and, when possible, unique identifying features of objects, including civilian shelters and humanitarian agency infrastructure, visible in high resolution imagery of the camps are identified. Objects are organized according to the United Nations Office for the Coordination of Humanitarian Affairs humanitarian cluster system and three other categories unique to this guide. Imagery provided by Google's Skybox Imaging for the creation of this guide can be explored online by following the directions included inside the report.
