OtsuFire (version 0.1.4)

Fire Scars, Severity and Regeneration Mapping Using 'Otsu' Thresholding

Description

Tools to segment fire scars and assess severity and vegetation regeneration using 'Otsu' thresholding on Relative Burn Ratio (RBR) and differenced Normalized Burn Ratio (dNBR) image composites. Includes support for mosaic handling, polygon metrics, post-fire regeneration detection, day-of-year flagging, and validation against reference datasets. Designed for analysis of fire history in the Iberian Peninsula. Input Landsat composites follow the methodology described in Quintero et al. (2025) .
