Use of data mining and spectral profiles to differentiate condition after harvest of coffee plants Discriminação de diferentes estados de plantios de café pós-colheita, por meio da técnica de mineração de dados e perfis espectrais

open access: yesEngenharia Agrícola, 2012
This study aimed at identifying different conditions of coffee plants after harvesting period, using data mining and spectral behavior profiles from Hyperion/EO1 sensor. The Hyperion image, with spatial resolution of 30 m, was acquired in August 28th, 2008, at the end of the coffee harvest season in the studied area.

Use of spectral data for estimating the relationship between iron oxides and 2:1 minerals with their respective reflectances
Uso de dados espectrais para estimar a relação entre óxidos de ferro e minerais 2:1 com suas respectivas reflectâncias

open access: yesSemina: Ciências Agrárias, 2013
Iron oxides and 2:1 minerals have a strong influence on the spectral behavior of soils. However, studies that address more deeply the relationship between them and their reflectances are scarce. Thus, the objective of this study was to estimate the relationship between iron oxides and 2:1 minerals with their reflectance factors, and assess whether such
