Yukon drone lidar surveys provide 30 cm resolution bare-earth Digital Terrain Models over segments of the Eastern Denali fault. The Yukon Geological Survey and Kluane First Nation collected the data to evaluate geothermal energy potential near Burwash Landing. The data reveals dextral offsets between 5 and 75 meters and vertical separation up to 20 meters.
Use Cases
- Mapping fault surface trace and geometry based on high-resolution hillshades.
- Assessing seismic hazard for geothermal drilling based on fault activity interpretations.
- Identifying zones of enhanced permeability for geothermal resources based on fault structure.
- Analyzing dextral offsets and vertical separation based on stream channel and hill slope data.
- Comparing fault strain concentration based on lidar versus ArcticDEM data.
Strengths
- 30 cm spatial resolution bare-earth Digital Terrain Models.
- Increased canopy penetration compared to existing spaceborne and airborne photogrammetric models.
- Data reveals specific dextral offsets ranging between 5 and 75 meters.
- Data reveals vertical separation ranging between 0 and 20 meters.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
