What is LiDAR? Light Detection and Ranging (Dewberry)

The search for the 43 missing students of the Ayotzinapa teacher training college, who disappeared in 2014, went high-tech last year.

The federal Attorney General’s office (PGR) invested more than 600,000 pesos (about USD $31,600) in high technology systems to attempt to locate the students, who disappeared during a night of violence in Iguala, Guerrero.

One of those systems was Lidar, which stands for Light Detection and Ranging, a remote sensing method that utilizes light in the form of a pulsed laser to measure variable distances to the Earth.

The process was used on the urging of the Interdisciplinary Group of Independent Experts (GIEI), the human rights advocacy group Centro Prodh and the Argentinian Team of Forensic Anthropology, all of whom have been involved in the investigation of the case.

They believed that Lidar might help authorities identify possible clandestine graves.
