This research mapped cropping patterns using time-series MODIS imageries in irrigated rice fields in West Java, Indonesia. This research was part of bigger research and serves as the background for more detail studies in the study area. This study is able to show the rice field distribution, its phenology metric, cropping pattern, and vulnerability to flooding. Specifically for irrigated rice fields under Ir. Djuanda (Jatiluhur) reservoir command area, the analysis allowed the identification of ongoing cropping patterns whether they are still aligned with the official cropping calendar.
