FESM 2025/26: NSW Fire Extent and Severity Mapping from Sentinel 2

Fire Extent and Severity Mapping (FESM) data for the Australian state of New South Wales, covering the interim 2025/26 fire year from July 1, 2025, to March 31, 2026. The dataset was developed by the NSW Department of Climate Change, Energy, the Environment and Water in collaboration with the NSW Rural Fire Service using a semi-automated machine learning framework based on Sentinel 2 satellite imagery. It maps wildfire extents greater than 10 hectares into standardized severity classes ranging from unburnt to extreme.

Use Cases

• Compare fire severity across different wildfire events based on the standardized severity classes.
• Model biomass loss and ecological impact based on fire severity metrics.
• Analyze spatial patterns of fire extent for wildfires larger than 10 hectares.
• Validate or train remote sensing models for fire detection using the Sentinel 2-based framework.

Strengths

• Provides standardized severity classes (unburnt to extreme) enabling cross-fire comparison.
• Covers a defined temporal range from July 1, 2025, to March 31, 2026, for the interim fire year.
• Includes all wildfires larger than 10 hectares within the specified period.
• Developed in collaboration with the authoritative NSW Rural Fire Service.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF and ZIP formats, which may require extraction and conversion for analysis.
