Finger Lakes Topobathymetric Lidar Elevation Model at 1m Resolution

Topobathymetric lidar data covering 301,150 acres in the Finger Lakes region of New York. The National Oceanic and Atmospheric Administration collected the data using a Riegl VQ-880-G sensor system across 23 missions between September and November 2019. The final dataset includes classified point clouds and 1-meter resolution Digital Elevation Models (DEMs) in GeoTIFF format.

Use Cases

• Modeling coastal erosion and flood risk based on integrated land and underwater elevation data.
• Mapping submerged aquatic vegetation (SAV) habitats based on the specific point classifications.
• Analyzing lakebed topography and water column structure using bathymetric and water surface classifications.
• Creating high-resolution terrain models for infrastructure planning based on the 1m pixel DEMs.

Strengths

• Covers a large area of 301,150 acres (~1,219 sqKm).
• Provides integrated topographic and bathymetric data in a single dataset.
• Includes detailed point classifications (e.g., ground, water surface, submerged vegetation) following ASPRS standards.
• Final DEM products have a high 1-meter pixel resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
