متن کاملCharacterising Bush Fires in Australia’s Top End using MODIS Active Fire Observations
This study used MODIS active fire detections and associated fire radiative power estimates to characterise bush fires in the savanna region of Australia’s Northern Territory. In contrast to other sensors MODIS has dedicated fire channels that rarely saturate over fires, enabling fire detections during the day and estimates of fire radiative power. Using number of dayand night-time fire detectio...

However. some use could be made of these wildfires fer forest mapping if developments in colour and false-colour (colour infrared) aerial photography were more fully exploited. The advantages that colour and false-colour aerial photography have over pan~ chromatic minus-blue aerial photography are analyzed...

متن کاملEstimating Risk Probabilities for Wildland Fires
In 2002. there were 88,458 fires reported on federal lands. These fires burned 6,937,584 acres and 2,381 structures costing taxpayers $1.6 billion for fire suppression. On average, 4,215,089 acres of federal lands burn annually. Forecasting wildland fire risk (occurrence and size) is important to fire managers who desire to know the risks of severe events well in advance of their happening. In ...
