abstract = "Remote sensing data has been widely used worldwide to estimate
crop fields parameters such as area.For that purpose, we use
automatic classification algorithms to identify different land
uses and land covers (e.g.agricultural and native vegetation),
groups of crops (e.g. annual and perennial crops) or crops species
(e.g.maize, sugarcane or soybean). For agricultural applications,
the ultimate goal is to be able to use remote sensingtechnology to
map crops in the specie level, and then to monitor them. One
essential input data used in theclassifications algorithms is the
spectral information of the ground targets (e.g. reflectance and
vegetationindices). Therefore, it is important to know the
spectral behavior of all targets. However, the ability of
oneclassifier to distinguish between plant species is probably
dependent on the amount of intraspecific variability. Inother
words, if a crop specie has high intraspecific spectral variation,
it will be difficult to classify this specieamong others. Thus,
the aim of this work is to analyze the intraspecific spectral
temporal variability of maizecrop. To accomplish that, spectral
data (OLI/Landsat-8) were acquired from first and second harvest
maize plots,cultivated over distinct management systems (irrigated
and non-irrigated), along two agricultural crop years,(2014/2015
and 2015/2016). We concluded that maize fields harvested in
different years, sowed in differentseasons, irrigated or not, have
a high temporal spectral variation, which cannot be associated
with these knowncharacteristics.",
