SPECTRAL DIFFERENCES OF TREE SPECIES BELONGING TO ATLANTIC FOREST OBTAINED FROM UAV HYPERSPECTRAL IMAGES
(Ieee, 2020-01-01)
The objective of this study is to evaluate the spectral difference between and within 11 tree species belonging to Brazilian Atlantic Forest located in the countryside of Sao Paulo State, Brazil. Tree species with different ...
Photogrammetric survey with UAV of strategic villages of Yocavil (Catamarca, Argentina)
(Springer Nature Switzerland AG, 2018)
In this paper we present a methodological synthesis from the first experiences in the use of Unmanned Aerial Vehicles or drones for the photogrammetric survey of strategic villages in the study area, the Santa María or ...
The use of unmanned aerial vehicles (Uavs) for estimating soil volumes retained by check dams after wildfires in mediterranean forests
(2021-03-01)
Check dams act as soil collectors during floods, thus retaining a large amount of sediments. The estimation of the soil volumes stored behind a check dam is a key activity for a proper design of these control works and for ...
Evaluation of hyperspectral multitemporal information to improve tree species identification in the highly diverse atlantic forest
(2020-01-01)
The monitoring of forest resources is crucial for their sustainable management, and tree species identification is one of the fundamental tasks in this process. Unmanned aerial vehicles (UAVs) and miniaturized lightweight ...
Comparing forest structural attributes derived from UAV-based point clouds with conventional forest inventories in the dry chaco
(MDPI AG, 2020-12-07)
Anthropogenic activity leading to forest structural and functional changes needs specific ecological indicators and monitoring techniques. Since decades, forest structure, composition, biomass, and functioning have been ...

(Instituto de Geociências e Ciências Exatas, Universidade Estadual Paulista, 2018)
Using thermal UAV imagery to model distributed debris thicknesses and sub-debris melt rates on debris-covered glaciers
(Cambridge University Press, 2023)
Supraglacial debris cover regulates the melt rates of many glaciers in mountainous regions around the world, thereby modifying the availability and quality of downstream water resources. However, the influence of supraglacial ...
Using UAVs and Photogrammetry in Bathymetric Surveys in Shallow Waters
(MDPICH, 2023)
The use of UAV (unmanned aerial vehicle) platforms and photogrammetry in bathymetric surveys has been established as a technological advancement that allows these activities to be conducted safely, more affordably, and at ...
