Thermal anomaly detection and classification

1. A system, comprising: a processor configured to: receive a set of images comprising multi-spectral band data, wherein a first image included in the received set of images is associated with location information; detect, at a first time, a thermal anomaly using the received set of images; determine that the detected thermal anomaly is a first ignition event having an associated detection time and associated location and, in response to the determination, generate an alert; and detect, at a subsequent time, a second ignition event, and selectively take an action regarding the detection of the second ignition event based at least in part on a determination of whether the second ignition event is associated with the first ignition event by updating boundaries of an existing fire in response to determining that the second ignition event is associated with the first ignition event; and a memory coupled to the processor and configured to provide the processor with instructions.

5. The system of claim 1 , wherein the processor is further configured to determine whether the detected thermal anomaly is associated with a wildfire.

6. The system of claim 1 , wherein detecting the thermal anomaly includes applying a cloud mask.

7. The system of claim 6 , wherein the processor is further configured to generate the cloud mask.

8. The system of claim 1 , wherein the processor is further configured to generate a fire mask.

9. A method, comprising: receiving a set of images comprising multi-spectral band data, wherein a first image included in the received set of images is associated with location information; detecting, at a first time, a thermal anomaly using the received set of images; determining that the detected thermal anomaly is a first ignition event having an associated detection time and associated location and, in response to the determination, generating an alert; and detecting, at a subsequent time, a second ignition event, and selectively taking an action regarding the detection of the second ignition event based at least in part on a determination of whether the second ignition event is associated with the first ignition even by updating boundaries of an existing fire in response to determining that the second ignition event is associated with the first ignition event.

10. A computer program product embodied in a non-transitory computer readable storage medium and comprising computer instructions for: receiving a set of images comprising multi-spectral band data, wherein a first image included in the received set of images is associated with location information; detecting, at a first time, a thermal anomaly using the received set of images; determining that the detected thermal anomaly is a first ignition event having an associated detection time and associated location and, in response to the determination, generating an alert; and detecting, at a subsequent time, a second ignition event, and selectively taking an action regarding the detection of the second ignition event based at least in part on a determination of whether the second ignition event is associated with the first ignition event by updating boundaries of an existing fire in response to determining that the second ignition event is associated with the first ignition event.
