LiDAR Data for Clarks River National Wildlife Refuge, 2011

Late fall-winter 2011 LiDAR data covering the 18,000-acre Clarks River National Wildlife Refuge in Kentucky. The dataset includes deliverables such as a 1-foot contour, bare earth DEM, hillshade, terrain, control points, DSM, intensity, LAS files, and shapefiles. It was collected by the Department of the Interior and published via Data.gov.

Use Cases

• Generate high-resolution digital elevation models based on the bare earth DEM data.
• Conduct terrain analysis for hydrological modeling using the provided terrain and hillshade layers.
• Map vegetation and structures for landscape management using the DSM and intensity data.
• Perform 3D point cloud analysis for environmental monitoring using the LAS files.

Strengths

• Covers a specific 18,000-acre protected area, providing focused environmental data.
• Includes multiple derived products like DEM, hillshade, and contour lines for immediate analysis.
• Data was collected in a single season (late fall-winter 2011), ensuring temporal consistency.

Limitations

• Associated metadata may not be fully compliant, which could hinder reproducibility.
• The dataset's last update date is listed as 2026-03-04, which suggests potential metadata issues regarding freshness.
• Column-level documentation is absent; field semantics must be inferred after download.
