Geospatial Technology Uncovers Mexico's Clandestine Graves

At Mexico's Center for Research in Geospatial Information Sciences, researchers use drones, hyperspectral images, spectroradiometers, and other technological approaches to locate the clandestine graves of missing persons. The researchers also have trained mathematical models with the coordinates of previously identified graves and site characteristics preferred by criminals, and developed tools that can detect sites with high concentrations of nitrogen (an indicator of decomposing bodies) in satellite images.
