Spatially-explicit and spectral soil carbon modeling in Florida. Profound shifts have occurred over the last three centuries in which human actions have become the main driver to global environmental change. In this new epoch, the Anthropocene, human-driven changes... ... Repository: BDPA Publication year: 2011
Comparative assessment of atmospheric correction of Landsat imagery using Modtran and dark object subtraction. Remote sensing by spectral imaging of the Earth's surface can be widely used, but only when the atmospheric influence is nullified and the data are reduced to surface reflectance units. The atmospheri... ... Repository: BDPA Publication year: 2012
New spectral index and machine learning models for detecting coffee leaf miner infestation using sentinel-2 multispectral imagery. The coffee leaf miner (Leucoptera coffeella) is a key coffee pest in Brazil that can cause severe defoliation and a negative impact on the productivity. Thus, it is essential to identify initial pest... ... Repository: BDPA Publication year: 2023
