Burn scar detection and its role in wildfire recovery
Burn scar detection uses satellite data and AI to map wildfire damage, aiding recovery and risk prevention
On this page
Wildfires cause severe environmental, economic, and social damage. A key part of wildfire recovery is assessing the full extent of the destruction. This is where burn scar detection helps—a technology-driven process that identifies and maps affected areas. Using satellite imagery, geospatial data, and AI tools, burn scar detection plays an important role in post-wildfire recovery efforts.

What is burn scar detection?
Burn scar detection is the process of analyzing geospatial data to identify areas affected by wildfires. These burned areas look different from their surroundings due to changes in vegetation, soil, and surface reflectance. By using satellite imagery, experts create maps that show the location and severity of burn scars. Advanced techniques, such as machine learning, enhance the speed and accuracy of these assessments.
Key data sources for burn scar detection
Burn scar detection relies on various data sources to accurately assess wildfire damage. These sources help identify burned areas, measure fire intensity, and analyze changes in the landscape.
Multispectral satellite imagery: Captures different light bands to highlight changes in vegetation and surface damage.
Normalized burn ratio (NBR): Measures the intensity and spread of burn scars.
LiDAR data: Provides a 3D view of the landscape to assess changes in terrain and structures after a fire.
How burn scar detection helps in wildfire recovery
Burn scar detection plays a key role in wildfire recovery by providing critical information for rebuilding efforts. It helps in the following ways:
Assessing environmental damage: Burn scar maps show vegetation loss, soil erosion risks, and ecosystem impact, guiding reforestation and restoration efforts.
Protecting water resources: Wildfires can damage watersheds, leading to sediment buildup and water contamination. Burn scar data helps identify areas that need erosion control and replanting.
Supporting disaster relief and resource allocation: Knowing the extent of the damage helps authorities prioritize recovery efforts, ensuring communities and ecosystems most in need get the necessary resources.
Predicting future risks: By analyzing burn scar data along with weather patterns and vegetation regrowth, scientists can identify areas at higher risk for floods or future wildfires.
Burn scar detection in the 2020 California wildfires
After the 2020 California wildfires, burn scar detection played an important role in recovery efforts. Remote sensing technology mapped over 4 million acres of burned land, identifying areas needing erosion control and ecosystem restoration. This data helped state agencies and environmental groups allocate resources for rebuilding habitats and communities. For more information, see Assessing California Fire Scars.
Summary and next steps
Burn scar detection is a vital tool in wildfire recovery, using satellite imagery, geospatial data, and AI to map fire-damaged areas. This process helps assess environmental damage, protect water resources, support disaster relief efforts, and predict future risks. By identifying burn scars, experts can guide reforestation, erosion control, and resource allocation. A notable example is the 2020 California wildfires, where burn scar detection helped map over 4 million acres, aiding recovery efforts. With advanced technology, burn scar detection continues to improve wildfire response and restoration.
