Daly City, California experienced landslides in December 2003 and January 2007, sending debris up to 290 meters downhill and 90 meters into the ocean. The U.S. Geological Survey collected high-resolution terrestrial LIDAR data to map these events. The dataset includes downloadable contour data, images, and metadata, along with geometric and volumetric measurements.
Use Cases
- Analyze landslide topography and morphology based on high-resolution LIDAR data
- Calculate volumetric changes and debris distribution based on geometric measurements
- Model coastal bluff erosion and failure mechanisms based on cross-section data
- Map landslide extent and impact on infrastructure based on topographic datasets
Strengths
- Data covers two distinct landslide events (December 2003 and January 2007) for comparative analysis
- Includes high-resolution topographic data collected using terrestrial LIDAR laser scanning
- Provides geometric and volumetric measurements and high-resolution cross-sections
Limitations
- Row count, column names, and sample data are unknown, limiting suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Last update date is unknown; freshness unverified
