Combining spectral and spatial information to map canopy damage from selective logging and forest fires

  title={Combining spectral and spatial information to map canopy damage from selective logging and forest fires},
  author={Carlos M. Souza and Dar A. Roberts and Mark A. Cochrane},
We propose a new spectral index, the Normalized Difference Fraction Index (NDFI), for enhanced detection of forest canopy damage caused by selective logging activities and associated forest fires. The NDFI synthesizes information from several component fraction images derived from spectral mixture models. Interpretation of the NDFI data is facilitated by a contextual classification algorithm (CCA) that enables accurate mapping of logging and fire-derived canopy damages. The CCA utilizes… CONTINUE READING
