             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.",
