The purpose of this study was to examine the pattern of annual drought variation using the standardized vegetation health index (SVHI) in the central highlands, Vietnam. The time-series imagery of daily MODIS products during the 2001-2020 period were used to compute land surface temperature and normalized difference vegetation index that are two primary parameters of the applied drought index. Besides, the standardized precipitation index (SPI), derived from 5 meteorological stations, was
