Background
BACKGROUND Forest Fires in Indonesia

  • 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 Fires in Indonesia

  • 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 Forest Fires in Indonesia

  • 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 Forest Fires in Indonesia

  • 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.
