Development of Drought Information System at Remote Sensing Application Center, National Institute of Aeronautics and Space (LAPAN)

Abstract

National Earth Monitoring System (SPBN) is a natural resource and disaster information system developed by Remote Sensing Application Center, National Institute of Aeronautics and Space (LAPAN), Indonesia. Drought information system is one of the SPBN disaster information products, consisting of Standardized Precipitation Index (SPI), Vegetation Greenness Level (TKV), and monthly accumulation of rainfall information. The quality of information products are improved towards data processing automation as well as provision of user-oriented products. The purpose of our research is to report the existing of drought information products at SPBN-LAPAN, to present briefly the automation process and also to analyze the result of the products. In this study, the “new” drought index information, which developed by blended of two datasets (TKV dataset that characterized agricultural drought and monthly rainfall dataset that characterized meteorological drought), using threshold method has introduced. The level of drought index is divided into five classes, namely cloud/water, severely dry, dry and normal
