Autor: Diogo Olivetti, Rejane Cicerelli, Jean-Michel Martinez, Tati Almeida, Raphael Casari, Henrique Borges, Henrique Roig

Publikováno v: Drones, Vol 7, Iss 7, p 410 (2023)

This work aimed to assess the potential of unmanned aerial vehicle (UAV) multi- and hyper-spectral platforms to estimate chlorophyll-a (Chl-a) and cyanobacteria in experimental fishponds in Brazil. In addition to spectral resolutions, the tested plat

Role of Climate Variability and Human Activity on Poopó Lake Droughts between 1990 and 2015 Assessed Using Remote Sensing Data

Autor: Frédéric Satgé, Raúl Espinoza, Ramiro Pillco Zolá, Henrique Roig, Franck Timouk, Jorge Molina, Jérémie Garnier, Stéphane Calmant, Frédérique Seyler, Marie-Paule Bonnet

Publikováno v: Remote Sensing, Vol 9, Iss 3, p 218 (2017)

In 2015, an emergency state was declared in Bolivia when Poopó Lake dried up. Climate variability and the increasing need for water are potential factors responsible for this situation. Because field data are missing over the region, no statements a
