Hotspots per year

NASA FIRMS (VIIRS S-NPP) vegetation fire detections per city/regency and year since 2015. Hotspots are not the same as burned area.

API

Responses use JSON and include stored data with its sources. Outside this site, the API needs an API key; downloads stay free. Credit the source and its licence.

Methodology

Data coverage

Each heat detection in the box 94°–142° E and 12° S–7° N: coordinates, satellite pass time, sensor confidence, and fire radiative power (FRP).

Processing

  • Only one satellite, NOAA-20, is counted. Two satellites can see the same fire, so adding them would double count it.
  • Counts cover the latest 24 hours ending at the most recent detection, including both day and night passes.
  • Points outside Indonesian city and regency boundaries are excluded. Each point belongs to exactly one area, so the area totals equal the national total.
  • Confidence follows the sensor's low, medium, and high classes. FRP is grouped as below 5 MW, 5 to below 25 MW, and 25 MW or above.
  • The same detection is not stored twice; its identity combines satellite, time, and coordinates.

Limitations

  • One point represents a pixel about 375 metres wide, not an exact fire location. One large fire may produce many points.
  • A hotspot does not always mean a fire; chimneys, field burning, or hot roofs may also be detected.
  • Clouds and thick smoke can hide heat from the satellite. No hotspot does not mean no fire.
  • The satellite passes about every 12 hours, day and night. NASA provides data roughly three hours after a pass.
  • Compared with NOAA-20 rows in SiPongi, our national count differs by less than 1%. Different administrative boundaries can explain the difference.
