Some Examples of Research Results and Activities Related to Forest Fires in Indonesia

(National Institute of Aeronautics and Space Republic of Indonesia)

background
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
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
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
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.

FIRE HAZARD MAPPING
  • Fire hazard mapping could be performed through the establishment of GIS Database
