abstract = "Besides the detection of fire focus, the orbital remote sensing
allows the use of a series of spectral indexes for the
identification of burn scars. The objectives of this work were to
avaliate the performance of indexes in the determination of the
burned area and to validate the detections of the Burn Monitoring
Portal. There were calculated nine indexes with spectral
information of the sensors Thematic Mapper and Enhanced Thematic
Mapper Plus (30m) of the Landsat series. There were raised heat
focus between june of 1988 and december of 2015 of all the
available orbital sensors in the Burn Monitoring Portal. The
indexes Normalized Burn Ratio and Char Soil Indexs had the best
performance in the identification of the burned areas. These
indexes differ from others because the consider spectral
information of the near and medium infrared regions. The more
critical period was from september to november. Of the total of
burns identified by data from the series Landsat, 37% also were
detected by the Burn Monitoring Portal. This low percentage of
success is due to the low spatial resolution of the sensors used
by this portal. Many fire focus werent detected because they were
in the opposite face of the sensors passing, or due to the cloud
cover, or yet by the ocurrence of fire between the period of the
sensors passing. Besides this limitation, these data are very
useful to determine the time of fire focus concentration.",
