CanLaBS v2: Canada-Wide Landsat Burn Severity at 30m Resolution, 1985-2024

CanLaBS v2 is a Canada-wide geospatial product mapping wildfire burn severity at 30-meter resolution. The dataset is produced by Natural Resources Canada and provides annual coverage from 1985 to 2024. It is an updated version incorporating Landsat Collection 2 data and an expanded fire perimeter record.

Use Cases

• Analyzing trends in wildfire burn severity over time based on the 1985-2024 temporal coverage.
• Modeling post-fire ecosystem recovery based on spectral change detection metrics.
• Detecting salvage logging activities within burned areas using the described random forest classification model.
• Assessing the spatial distribution of fire impacts across Canadian landscapes at a 30-meter scale.

Strengths

• Provides consistent 30-meter resolution data across Canada from 1985 to 2024.
• Uses Landsat Collection 2 inputs for improved radiometric calibration and geometric accuracy.
• Salvage logging detection model achieved an overall accuracy of 90.6% and a Cohen’s kappa of 0.87.
• Aligns with the National Burn Area Composite (NBAC) fire perimeter record for consistency.

Limitations

• 6.9% of burned pixels have missing data due to the revised post-fire gapfilling strategy.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or temporal bias inherent to the source satellite imagery and fire perimeter records.
