Mapping Ecosystems in the Peruvian Andes Using Hyperspectral Imagery and Machine Learning

Daria-Ioana Radu, Hugo Lepage, Eustace P. G. Barnes, C. H. W. Barnes

Mapping the Peruvian Andes has high ecological value because its ecosystems are immensely diverse. These mountains shelter numerous endemic species that could be protected if informed decisions are made when delineating conservation zones. Rigorous analysis of high-altitude regions traditionally requires multiple field …

Physical and chemical techniques for a comprehensive characterization of river sediment: A case of study, the Moquegua River, Peru

L. De Los Santos Valladares, Arquimedes Vargas-Luque, L. E. Borja-Castro, R. A. Valencia-Bedregal et autres

River sediment is comprised of complex mineral systems composed by different kinds of organic and inorganic matter, and thus, is difficult to characterize. Besides, some standard techniques, such as X-ray diffraction (XRD), energy dispersive X-ray (EDX), optical and scanning electron microscopy, Fourier …
