Compute normalized difference spectral indices (NDVI, NDWI, NBR) from Sentinel-2 or Landsat time series. Produces temporal aggregates (mean, max, min, stddev, range) aligned to the terrain analysis grid.

Inputs:

  • Satellite Imagery Package - ZIP file from Search & download Planetary Computer containing Sentinel-2 or Landsat band GeoTIFFs and manifest.json with time_series;

  • Spectral Index. Type of normalized difference index to compute:

    • NDVI (Vegetation) (NDVI);

    • NDWI (Water) (NDWI);

    • NBR (Burn Ratio) (NBR);

  • Generate series - tick to generate series rasters (max, min, std etc.) if multiple inputs are provided.

Outputs:

  • ZIP archive with spectral index aggregates, statistics, and manifest;

  • Human-readable summary of the spectral index results;

  • JSON manifest string describing all outputs.
