This study was conducted to improve a global crop calendar product using satellite-sensed vegetation indexes. In this study, we newly used EVI and SAVI, in addition to NDVI, to define crop calendar by phenological analysis. Using a global cropping map, parameters to define planting and harvesting dates are determined to three vegetation indexes. Estimated crop calendars using three vegetation indexes agree with a statistical crop calendar at approximately same level. Improvements of global crop calendar using EVI and SAVI are not captured. On the other hand, determining cropping parameters brings about improvement of the crop calendar, which causes an improvement of analyzed agricultural water usage.
