2022 NOAA Topobathy Lidar DEM for Washington Island, Wisconsin

NOAA OCM's 2022 dataset provides a 1-meter resolution topobathy Digital Elevation Model for approximately 219 square miles along the shores of Green Bay, Wisconsin. The data were collected by Dewberry using a CZMIL Super Nova system from July 19 to August 16, 2022. It consists of 2,630 individual 500m x 500m GeoTiff files.

Use Cases

• Modeling coastal erosion and sediment transport based on integrated topographic and bathymetric elevation data.
• Assessing flood risk and storm surge impacts based on high-resolution coastal elevation models.
• Creating nautical charts and navigational aids based on detailed bathymetric seafloor mapping.
• Analyzing shoreline change and habitat mapping based on the 1-meter grid resolution.

Strengths

• High-resolution 1-meter grid spacing for detailed elevation modeling.
• Covers approximately 219 square miles, providing substantial spatial coverage.
• Data acquisition period is precisely documented from 20220719 through 20220816.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
