description=Compute the Standardized Agricultural Drought Index (SADI) using Google Earth Engine, Landsat 7 and CHIRPS precipitation data.

about=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.

changelog=
    1.3.0 (2026-06-12)
    - Direct GEE authentication via GCP Project ID + OAuth2; GCP project ID
      persisted in QGIS profile across sessions
    - Computation moved to QThread — UI stays responsive during processing
    - Results panel with Charts, Prediction and Text Summary tabs
    - Markov chain 4-state drought prediction and OLS linear trend projection
    - SPI computed from CHIRPS daily precipitation
    - Proper VHI (VCI + TCI) mapped per image before annual mean
    - Per-year time-series gated by batch size check — fixes empty-collection
      errors for years with no Landsat coverage
    - Dynamic year range computed from current date; end year auto-set to last
      fully elapsed season
    - Geometry handling: auto-reproject to WGS84, MultiPolygon dissolve
    - Charts and text summary exportable as PNG / clipboard copy
    0.1 (2024-03-03)
    - Initial release
