How are hotspots/fires detected?
The hotspot/fire detections are produced using the same algorithm as the standard MODIS MOD14 fire and thermal anomalies product. Fire detection is performed using a contextual algorithm that exploits the strong emission of mid-infrared radiation from fires. The algorithm examines each pixel of the MODIS swath, and ultimately assigns to each one of the following classes: missing data, cloud, water, non-fire, fire, or unknown.
