change_burn
Detect fire scars and classify burn severity by computing the differenced Normalized Burn Ratio (dNBR) from pre-fire and post-fire NIR and SWIR reflectance values.
Instructions
Fire scar / burn severity detection using dNBR (differenced Normalized Burn Ratio). Computes NBR for pre-fire and post-fire dates from NIR and SWIR bands, then classifies burn severity.
