Propuesta de un nuevo índice para la cartografía de áreas quemadas: aplicación a imágenes NOAA-AVHRR y Landsat-TM

A new spectral index adapted to burned land mapping is presented in this paper. The index is named Burned Area Index (BAI). It is based on the inverse spectral distance from each pixel to a burned convergence point, as defined by typical burned areas in the Red and NIR bands. Laboratory spectro-radiometry measurements, as well as high and low resolution satellite images are used in testing the usefulness of this index.
