研究目的
To review the application of various satellite data in fire detection and mapping, and to evaluate different algorithms developed for fire detection from satellite data.
研究成果
Remote sensing is crucial for identifying and delineating coal fires to prevent economic loss. Different remote sensing approaches have their advantages and limitations, and the choice depends on the specific study requirements. Night-time or predawn data are recommended for more accurate results. The development of UAV/drone based sensors offers higher spatial resolution for fire delineation.
研究不足
The spatial resolution of satellite data can limit the detection of small or deep coal fires. Daytime data may include solar effects, reducing accuracy. The selection of a specific sensor algorithm for global fire products is challenging.
