Hyperspectral imaging to map Gran Dolina's oldest sediments and fossils in infrared

Phys · · 448 words · By Spanish National Research Centre

The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) and the Instituto Tecnológico de Castilla y León (ITCL) are collaborating to use hyperspectral imaging on the Gran Dolina Site in Spain. The project aims to use visible and infrared light analysis to better characterize sediments and fossils from approximately 1 million years ago using non-destructive methods.
