The locations of fires are determined by heat anomalies detected by the satellites. Having a satellite based method of detecting fires is valuable as it provides firefighters an advanced view of the current situation in nearly real time. This can save lives and property.
The size of the points corresponds to the "Fire Radiative Power" which is the power output of the fire in MegaWatts (MW). Drag the slider to control what the cut off for the MW's of a fire to be shown. (Note that slider scale is nonlinear.)
The color of the points corresponds to the "Brightness Temperature" of the fire, or it's temperature in Kelvin (K). Colors chosen for legend represent the lowest and highest values seen in the dataset.
As a result sometimes the points are not entirely accurate. The data from the satellites is paired with a confidence score, from between 0-100. With 0 being no confidence in the datapoint and 100 being total confidence. Drag the slider to set the confidence minumum.
