Assessment of surface water at the Sobradinho reservoir under the effects of drought using multi-temporal Landsat Images
(2016-01-01)
The matrix of energy generation in Brazil is predominantly hydroelectric power. Consequently, the reservoirs need constant monitoring due to the large volume of artificially dammed water. Images from remote sensing can ...
Two-wavelength whole-field interferometry setup for thermal lens study
(2012-12-01)
In this paper we present a new approach for thermal lens analysis using a two-wavelength DSPI (Digital Speckle Pattern Interferometry) setup for wavefront sensing. The employed geometry enables the sensor to detect wavefronts ...
Wavelets and decision trees for target detection over sea surface using cosmo-skymed SAR data
(2011-10-19)
We are investigating the combination of wavelets and decision trees to detect ships and other maritime surveillance targets from medium resolution SAR images. Wavelets have inherent advantages to extract image descriptors ...
ASSESSING 2016 DROUGHT PROGRESSION OVER INDIA USING REMOTE SENSING DATA FOR THE PERIOD 2006-2015

Determining large scale actual evapotranspiration using agro-meteorological and remote sensing data in the northwest of Sao Paulo State, Brazil
(Int Soc Horticultural Science, 2014-01-01)
The best irrigation management depends on accurate estimation of reference evapotranspiration (ET0) and then selection of the appropriate crop coefficient for each phenological stage. However, the evaluation of water ...
Reservoir cascades in sequence and their effect in water reflectance
(World Scientific And Engineering Acad And Soc, 2008-01-01)
The modification of a river in several reservoirs with purpose of hydroelectric power provides important environmental modifications in the aquatic system. In this sense, this work has the objective of identifying the ...
Detecting citrus huanglongbing in brazilian orchards using hyperspectral aerial images
(2019-06-04)
Brazil is one of the world leaders in citrus plantation, and the production of orange juice is economically important in the export scenario, being regarded as a fundamental agricultural commodity in Brazil. The worst ...
Development of a filter for phycocyanin bio-optical estimation
(2014-01-01)
Phycocyanin is a unique pigment for cyanobacteria in inland waters which has been identified by remote sensing. Several band ratio algorithms were developed to estimate and identify phycocyanin using its absorption spectral ...
Shadow detection improvement using spectral indices and morphological operators in Urban Areas in high resolution images
(2015-01-01)
While high-resolution remote sensing images have increased application possibilities for urban studies, the large number of shadow areas has created challenges to processing and extracting information from these images. ...
