Mapping of Suspected Burial Sites as an Aid for the Search of the Missing

While techniques relying on Geographic Information Science (GIScience) have been applied to a number of fields over recent decades, there are still many fields wherein experimental work on applied spatial modeling is just now opening up opportunities for advancing scientific knowledge. For the last six years, I have had the honor of working with some ground-breaking, forensic anthropologists to advance scientific knowledge surrounding humanitarian aid issues. Specifically, we examine how to use GIScience and spatial statistics to model wartime killer behaviors. Accurate, precise models of these behaviors may help identify lost burial sites and eventually allow families to recover the remains of loved ones – the missing civilians and soldiers. This work has involved research on acts of violence committed in political emergencies in many complex scenarios such as the former Yugoslavia and in enduring conflicts like Nagorno-Karabakh. I have had the chance to personally work with some  amazing collaborators in this field, including Dr. Derek Congram, Hugh Tuller, Matt Vennemeyer, Michael Kenyhercz, and several current and former staff at the ICRC (financially supported this work). In fact, many of authors in this edited collection have inspired and informed our research. 

The below article represents a small sample of lessons learned from these collaborations and our experimental work. This article is an accepted manuscript for the Forensic Science International special issue on “Humanitarian Forensic Action”. Accepted manuscripts are under a 12-month embargo for many academic sharing sites, but can be immediately shared on author’s personal website.

Watershed Delineation GIS – Open Education Resource

The above slides are a tutorial for people who want to learn how to do watershed delineation using Shuttle Radar Topographic Mission (SRTM). The tutorial is free and licensed as CC BY SA. It can be downloaded here.

The tutorial uses SRTM 1 Arc-Second (30 meter resolution) data to map the Faro River basin near the Cameroon and Nigeria border. The methods can be applied to any region as the data for the tutorial is free (open data) from USGS that can be downloaded here http://earthexplorer.usgs.gov/.

I created this tutorial for my Advanced Geographic Information Science students at UBC in March 2016. The tutorial uses ArcMap 10.3, so you will need access to that software and the software’s Spatial Analyst license.

Let me know if you find it useful or see something that could be improved!

Download Options

  1. You can download the slides from SlideShare.
  2. The data is free from USGS Earth Explorer.
