abstract = "The objective of this work was to develop a methodology for
mapping cultivated areas with summer crops (soybean and corn) in
the state of Paran{\'a} using MODIS sensor images for the crop
year of 2013/2014. For classification the Random Forest algorithm
was used. It is hard to differ soybean from corn with MODIS. Due
to the heterogeneous and high spectral-temporal dynamics of corn
and soybean, including proximity or distinction in the sowing and
initial development in mesoregions of the state the Random Forest
algorithm was applied in order to present a clear differentiation
between crops. For the evaluation of the spatial accuracy of the
mapping, the Landsat8 / OLI satellite images were used. These
images served as reference to generate the error matrix. The
proposed method obtained a kappa index of 0.9678, which is
considered excellent, and a global of 98.61%, which also
represents an excellent index. However, the results obtained from
the mapping underestimated the area destined to the culture of
Corn in about 50% and overestimated the soybean area by about 24%.
Besides that, the methodology was successful in mapping soybean
and corn crops in the state of Paran{\'a} for the crop year
2013/2014, since the method is fast and inexpensive. Thus, the
results indicate that the method is efficient for mapping the
summer crops. Nevertheless, it is necessary to make some
improvements to minimize the difference between the mapping result
and the official data.",
