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

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.

Why it matters

As part of this initiative—aimed at strengthening links with the private and industrial sectors in order to foster technical innovation and knowledge transfer—researchers have studied the infrared response of the oldest levels of the Gran Dolina Site in the…

Common ground

These are levels TD3 and TD4, which began to form around 1 million years ago, when groundwater receded from the cave and sediments from the slopes of the Sierra de Atapuerca began to accumulate within it.

Perspective signals
