Researches aiming greenhouse gases reduction have been motivated by the impact of extreme climate events around the world. In Brazil, sugar cane is the main source for ethanol production to replace fossil fuels. In this context, remote sensing imagery has been widely used to monitor sugar cane harvests and to support scientific research. In this paper, we propose a methodology based on data clustering to analyze NDVI time series obtained from AVHRR/NOAA satellites and monitor the growing cycles of sugar cane crops. The experiments show that our approach can identify areas with similar development patterns also considering different growing crops seasons.
