Chesapeake Bay Topobathy Lidar DEM at 1m Resolution, 2022-2023

3251 square kilometers of topobathy 1-meter gridded Digital Elevation Model data for the Chesapeake Bay coastline in Virginia. Woolpert collected the data using a Leica Hawkeye4X system from November 3, 2022, through March 5, 2023. The dataset consists of 5000m x 5000m tiles generated from ground and bathymetric point classes.

Use Cases

• Model coastal erosion and inundation based on the 1-meter resolution elevation data.
• Analyze seafloor topography and nearshore bathymetry for navigation and habitat mapping.
• Create high-resolution terrain models for coastal zone management and planning.
• Integrate land and underwater elevation for hydrodynamic and sediment transport studies.

Strengths

• Covers approximately 3251 square kilometers of coastline.
• Provides 1-meter resolution gridded elevation data.
• Combines topographic and bathymetric (ground and seafloor) data in a single model.
• Data collection period is explicitly stated as November 2022 to March 2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The available file formats (PDF, HTML) suggest metadata or reports, not the primary raster data, which may require separate discovery.
