abstract = "The State of Mato Grosso is characterized by soybean cultivation
in summer seasons. As the agricultural sector has an important
participation in economy, the implementation of monitoring and
systematic mapping tools is important for the strategic planning.
Facing this demand, the connection of field data, orbital data and
geostatistical techniques appears as a tool in the attempt to
ensure accuracy of the generated information. This paper presents
and evaluates the Soja Sat initiative, which aimed to map the
areas cultivated with soybeans in Mato Grosso between the
2000/2001 and 2010/2011 harvests. A combination of field data,
which was obtained in partnership with Bom Futuro SA Group, daily
vegetation data, which was derived from the Enhanced Vegetation
Index (EVI) derived from the Moderate Resolution Imaging
Spectroradiometer (MODIS), that is sensitive to biomass variations
during the phenological cycle and geostatistical techniques were
used. The period of analysis for validation involved the 2010/2011
harvest due to the relevance in the production and the
availability of geographical delimitation. Aiming at validating
and demonstrating the accuracy of the mapping, 5 agglomerates of
farms were chosen for reference. Subsequently, from a point
analysis of the soybean plots and a reference map that is derived
from the TerraClass project, reliability indexes were generated
through a confusion matrix. The results obtained presented high
agreement with the field data. The Global Accuracy (0.92) and the
Kappa Index (0.84) indicated that the proposed method was
efficient for the mapping soybean crops in the 2010/2011 harvest
in Mato Grosso.",
