Compute the Standardized Agricultural Drought Index (SADI) using Google Earth Engine, Landsat 7 and CHIRPS precipitation data.
SADI Processor computes the Standardized Agricultural Drought Index for any user-defined area of interest using Google Earth Engine cloud processing. The plugin calculates NDVI, VCI, Land Surface Temperature, TCI, VHI and the full DI classification chain to produce a SADI map layer and a multi-year time-series. Results are presented in an interactive panel with three tabs — Charts (NDVI, SADI, SPI trends), Prediction (Markov chain next-state probabilities and linear trend projection), and a Text Summary suitable for reporting. Authentication uses direct GEE OAuth2 with your GCP Project ID; no third-party QGIS plugin dependency is required. Precipitation data comes from CHIRPS daily composites and is standardised to SPI client-side.
