abstract = "Obtaining effective technologies for quantifying and forecasting
the monitoring of agricultural crops highlights the search for
methodologies that provide this information before harvest. The
study of agricultural monitoring and/or estimated yields of winter
crops using vegetation indices derived from multi-temporal data
from Modis sensor, is being studied in the search for greater
objectivity to the values generated. In this context, the research
aims to map areas with winter crops (wheat and corn 2nd harvest),
using time series of vegetation index EVI from the Modis sensor of
Terra and Aqua satellites, the 2013 harvest for the state of
Paran{\'a}. As a way to adjust the mapping through Modis (250
meters) sensor visual analysis, where images of high spatial
resolution (30 meters) to identify the desired cultures were used
was performed. Checking the quality of the mapping was assessed by
using the error matrix analysis of accuracy as the Global Accuracy
and the Kappa coefficient. For corn (2nd crop) and wheat, the
overall accuracy reached values of 92.5% and 87.3% for corn (2nd
crop) and wheat respectively, reaching the minimum acceptable
value that is 85%. The Kappa index was classified as excellent and
very good for the corn (2nd crop) and wheat respectively.",
