Abstract�� By detecting forest fire happened in Australian southeast from remote sensing imagery to demonstrate the application ability of HJ-1B satellite in disaster. After analyzing the character of HJ-1B IRS B07 system parameters and data trait, a normalized forest fire index, ��K��u, was constructed. Pixels are potential fore fire points where ��K��u are greater than 0.40. Cloud dazzling points and surface high-temperature points are the main noises disturbing the fire point detection. MODIS 250m spatial resolution band 1 and band 2 were used to get normalized difference vegetation index(NDVI) for the lack of HJ-1B data earlier than the fire happened date and its results are suitable for the forest fire detection. The compare of detection results by HJ-1B and moderate-resolution imaging spectroradiometer(MODIS) fire product, MOD14, shows that HJ-1B is better than MOD14 on presenting fire spatial structure for the reason of its higher spatial resolution, 300��m.
