Some Examples of Research Results and Activities Related to Forest Fires in Indonesia Agus Hidayat (National Institute of Aeronautics and Space Republic of Indonesia)
BACKGROUND • In Indonesia forest fire seems to be a regular phenomenon that could happen every year • The 1997 fire episode was the most serious forest fires in the last 15 years. • Official government figures put the 1997 forest fires in Indonesia at 263,991.21 hectares and land fires at 119,878 hectares. • Comparison : In 1982-1983, an estimated 3.5 million hectares of forest in East Kalimantan were damage by drought and subsequent fires.
Reasearch & Activities: • Forest Fire Prevention : drought monitoring using Vegetation Index, Fire Danger Rating System (FDRS) • Forest Fire Detection and Monitoring : Hot Spots Detection and Monitoring (using low resolution satellite data), fire detection and monitoring using high resulution data.
Calculating Vegetation Index • Collect daily NOAA-AVHRR data (Channel 1 and 2); • Perform radiometric correction; • Perform geometric correction; • Calculate NDVI = (Ch2-Ch1) / (Ch1+Ch2); • Perform data classification; • Data analysis.
HOT SPOTS DETECTION • Collect NOAA-AVHRR Data, Channel 3 and 4; • Perform data calibration by calculating Gain and Intercept; • Calculate the radiance of each pixel for channel 3 and 4 data; • Convert the radiance values into brightness temperature; • Tb3-Tb4 > 20o Hot Spots/Fires Spots (based on LAPAN ground check experience); • Perform geometric correction; • Display hotspots and their coordinates.
