What are the advantages and disadvantages of using satellite remote sensing to monitor forest fires?

Summary：Satellite remote sensing utilizes polar-orbiting meteorological satellites, land resource satellites, geostationary satellites, and low-orbit satellites to detect forest fires. These systems can identify hotspots, monitor fire spread, provide timely information on the fire situation, generate forest fire risk forecasts, and estimate the area burned using digital satellite data.

Key Words：

Satellite remote sensing utilizes polar-orbiting meteorological satellites, land resource satellites, geostationary satellites, and low-orbit satellites to detect forest fires. These systems can identify hotspots, monitor fire spread, provide timely fire-scene information, generate forest fire risk forecasts, and estimate the area burned using digital satellite data.

Advantages:

They offer wide detection coverage, rapid data acquisition, and continuous data streams that capture the dynamic evolution of the fire; data collection is unaffected by terrain, and the imagery is realistic.

Disadvantages:

Accuracy is low, requiring significant ground-based manpower, material resources, and funding for verification—particularly in remote areas with poor accessibility, where verifying the fire situation is crucial.

By the time a hotspot spans three pixels, the fire has essentially already become a major incident.

The time lag between the satellite pass and notifying firefighting teams of the need for verification prevents effective early intervention (i.e., extinguishing the fire while it is still small and manageable).
