Agricultural drought is a natural hazard that characterized by shortage of water supply. In recent decades, the scientists usually deal with phrases Agricultural drought monitoring as an essential component of drought risk management and using remote sensing (RS) and Geography Information System (GIS) based on drought indicators, proposed and widely used in the field of drought monitoring. This paper presents some agricultural drought indicators to generate a suite of drought levels at monthly, seasonal, and annual time scales for the North Central regions, Vietnam. MODIS satellite image data and threshold drought lever were classified according to the measurement data survey that regarding the law of drought in Vietnam. Based on calculating NDVI index, our research built maps of VCI, LSWI, VTCI indicators. All the data sets are being produced and updated in near-real time to provide information about the onset, progression, extent, and intensity of drought conditions at research region. | Remote sensing and GIS of agricultural drought monitoring in the north central region, Vietnam
