Post-Fire Landslide Hazards: LiDAR and UAS Data from Oregon Wildfire Sites

Data from 2017 to 2020 captures post-fire geologic hazards at sites affected by the 2020 Holiday Farm, 2020 Archie Creek, and 2017 Eagle Creek Fires in western Oregon. The dataset contains high-resolution point cloud data acquired via terrestrial laser scanning and structure-from-motion from drone imagery. It was authored by Adam Booth and last updated in February 2025.

Use Cases

• Characterizing debris flow and rockfall hazard based on perishable data captured 1-2 months after fires.
• Mapping debris flow runout tracks and deposit extents based on UAS data from sites like Dodson.
• Analyzing topographic changes over time based on repeat survey data from burned forest and road areas.
• Modeling post-fire landslide risk based on high-resolution LiDAR and point cloud data from specific creek and rock sites.

Strengths

• Contains high-resolution point cloud data for detailed topographic analysis.
• Includes perishable data captured 1-2 months after the 2020 fires, providing immediate post-event snapshots.
• Covers multiple significant fire events (2017 Eagle Creek, 2020 Holiday Farm, 2020 Archie Creek) across western Oregon.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• Data freshness should be verified as the last metadata update was 2025-02-10.
