2011 Georgia Lidar Digital Elevation Models for Four Counties

NOAA Coastal Services Center contracted Woolpert, Inc. to collect high-resolution LiDAR elevation data for Burke, Richmond, Lincoln, and Columbia counties in Georgia in 2011. The data includes classified LAS point clouds and hydrologically flattened raster DEMs with a nominal pulse spacing of 1.0 meter and a 4-foot pixel resolution. Final products were delivered in ESRI Floating Point Grid and later converted to GeoTIFF format with vertical units in feet.

Use Cases

• Generate high-resolution bare-earth terrain models based on the hydrologically flattened DEMs.
• Analyze vegetation and man-made structure heights based on the full classified LAS point cloud data.
• Perform hydrological and watershed modeling based on the hydrologically flattened breaklines and DEMs.
• Create topographic maps and visualizations based on the 1.0-meter nominal pulse spacing LiDAR data.

Strengths

• Data was collected with a high-resolution nominal pulse spacing of 1.0 meter.
• Final products include multiple formats: classified LAS point clouds, 4-foot pixel raster DEMs, and hydrologically flattened breaklines.
• Data collection was conducted under a specific NOAA contract (EA133C11CQ0010) by a named contractor, Woolpert, Inc.

Limitations

• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• The dataset's row count and total file size are unknown, which may limit suitability assessment.
• The description does not specify the license under which the data is distributed.
