abstract = "Vegetation fires in South America are operationally monitored by
INPE in images from distinct polar and geostationary satellites.
Fundamental in this system is to ascertain the fire pixel data
concerning omission and commission errors in order to determine
their effective use in fire control, statistics, and policies, and
in derived products as estimates of biomass burning emissions. In
this paper the INPE-generated fire pixels are verified against
fire scars manually mapped in TM/Landsat-5 images during 40 days
in the area of the National Park of Serra da Canastra, MG, on
Sept-Oct/2007. The 8,650 km2 analized belong to the
Cerrado/Savanna biome, which in the last decades has undergone
anthropic stress with intensive fire use. 442 INPE fire pixels and
395 scars were obtained. If the location accuracy allows for a
deviation up to the maximum pixel size (~3km for MODIS, ~4km for
AVHRR, ~5km for GOES and ~7km for Meteosat), omission errors were
20% and commission errors were negligible. Image navigation errors
of a few kilometers in geolocation which may occur in the images
also contribute to this deviation. A comparison between the MODIS
fire detections using the INPE and the NASA/UMD Collection 5
algorithms is also included, with the latter producing more and
better located fire pixels. Recommendations for future algorithms
are: pixel size (i.e., scanning angle) inclusion to indicate the
fire nominal accuracy, and the use of topography data in
conjunction to the sensor scanning angle and direction to analyze
missed detections in steep mountain slopes.",
