Comparative Analysis of Normalized Difference Water Index (NDWI) Methods in Continental Wetland
Anuário do Instituto de Geociências - UFRJ, 2018 The remote sensing data, like radiometric indices, represent alternative data generation sources that can help us understand the natural processes that occur in the Pantanal. The Normalized Difference Water Index (NDWI) is a partially known method in the scientific community which makes geotecnologies use. Although, its use and application still causes

Remote Sensing in Ecology and Conservation, EarlyView.Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.

Development of an empirical model for chlorophyll-a and Secchi Disk Depth estimation for a Pampean shallow lake (Argentina) [PDF]
, 2017 Shallow Pampean lakes are located in the most productive plain of Argentina. They are highly variable in salinity, turbidity and surface area. Laguna Chascomús has been monitored as a representative example of them.

Remote Sensing in Ecology and Conservation, EarlyView.Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Oil spill detection using optical sensors: a multi-temporal approach [PDF]
, 2018 Oil pollution is one of the most destructive consequences due to human activities in the marine environment. Oil wastes come from many sources and take decades to be disposed of.

Wildlife Biology, EarlyView.As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

The impact of global changes on agriculture: the case of Ivorian Basin of Comoe River. [P-3330-16] [PDF]
, 2015 Since some decades, the Ivorian Comoe river Basin faced environmental and climatic changes. As one of rainfed agriculture leading forces, climate conditions display (here) a major role in agriculture transformations.

Assessing habitat suitability for black grouse broods at the bioregional scale
Wildlife Biology, EarlyView.The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

L'apport de l'imagerie à haute résolution spatiale à la cartographie du risque de crue torentielle
Revue Française de Photogrammétrie et de Télédétection, 2014 Dans ce travail nous étudions le flanc sud du volcan Merapi (Indonésie) dévasté par la grande éruption de 2010 (IEV 4). Nous poursuivons trois objectifs : (1) Identifier les dépôts pyroclastiques et de lahars grâce à la classification «orientée-objet ...
