• Potential Fire Activity (GOES)

  Pulled from NOAA's GOES-16 and GOES-17 using Google Earth Engine, this is an estimate of current fire activity in the last hour. Updated every 10 minutes, this dataset is pulled from two of NOAA's geosynchronous satellites.

  Prone to false positives. Bodies of water, solar farms, and other energy infrastructure can cause false positives.

  This data is highly imprecise and has some accuracy issues -- it should only be used as a indication of possible fire activity.

• Current & Minor Incidents (WFIGS)

  These incidents are sourced from and maintained by various agencies. They are broken into two groups, "current" and "minor" based on wheter or not the FireMgmtComplexity attribute is defined in order to reduce clutter and elevate larger incidents.
  • WFIGS - Current Wildland Fire Locations

• Current Perimeters (WFIGS)

  These perimeters are sourced from and maintained by various agencies. They update sporadically and do reflect the most accurate confirmed fire and burn area perimeters.

• Hotspots (VIIRS + MODIS)

  Collected every 12 or so hours by NASA satellites. Each dot represents a heat signature deteced beyond various thresholds within the last ~48-60 hours. **Prone to false positives.** Energy infrastructure and other heat sources can cause false positives. *This data is highly imprecise and has some accuracy issues -- it should only be used as a indication of possible recent fire activity.*
