The potential for operational monitoring of selectively logged forest using vegetation index in the brazilian Amazon. This work presents a approach for monitoring forest degradation in the Brazilian Amazon using a multi-temporal dataset of Landsat-8 imagery. We use a Normalized Burned Ratio (NBR) for detecting select... ... Repository: BDPA Publication year: 2019
New vegetation index for monitoring coffee rust using sentinel-2 multispectral imagery. Coffee Rust (Hemileia vastatrix) is considered the primary coffee disease in the world. The pathogenic fungus can find favorable environmental conditions in different countries, constantly threatening... ... Repository: BDPA Publication year: 2023
Remote sensing environmental indicators for monitoring spatial and temporal dynamics of weather and vegetation conditions: applications for Brazilian biomes. Abstract: The SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm and the radiation use efficiency (RUE) model were coupled to test large-scale remote sensing environmental indicators... ...

Optimization of sampling and monitoring of vegetative flushing in citrus orchards. Citrus trees produce flushes throughout the year, but there are no criteria established for a precise shoot monitoring in orchards under tropical climate. Methods for quantification of flush dynamics... ... Repository: BDPA Publication year: 2020
Monitoring the temporal dynamics of four vegetation cover types from the Pantanal using the wavelet transform applied to a time-series of EVI/MODIS data. Although one of the most preserved ecosystems in Brazil, the Pantanal suffers under problems such as fire, deforestation and changes in the flood and drought cycles. Monitoring all the extension of th... ... Repository: BDPA Publication year: 2011
Assessment of vegetational indices applied to sugarcane monitoring using Rapideye images. Rapideye sensor have been operating since 2009 and was one of the first multispectral (5 bands) sensors to operate as part of a satellite constellation (5 satellites), able to provide a massive stock... ...

Forest Cover Changes in Tropical South and Central America from 1990 to 2005 and Related Carbon Emissions and Removals. This paper outlines the methods and results for monitoring forest change and resulting carbon emissions for the 1990-2000 and 200-2005 periods carried out over tropical Central and South America. To p... ... Repository: BDPA Publication year: 2012
Comparing forest restoration canopy cover measurements using RGB and multispectral sensors onboard drones. Abstract: Remotely Piloted Aircrafts (RPA) coupled with Red-Green-Blue (RGB) sensors have a high potential to monitor Forest Restoration (FR), but multispectral sensors onboard RPA are more expensive... ...
