Topobathy Lidar DEM of Maryland Coastline, 2022-2023

A 1-meter resolution Digital Elevation Model (DEM) derived from topobathy lidar data collected along the Chesapeake Bay coastline from Bethany Beach to Chincoteague, Maryland. Woolpert collected the data using a Leica Hawkeye4X system between November 3, 2022 and February 5, 2023. The dataset covers approximately 3251 square kilometers and is provided as 5000m x 5000m tiles.

Use Cases

• Modeling coastal erosion and flood inundation based on the 1-meter resolution elevation data.
• Analyzing seafloor topography and submerged features based on bathymetric point classes.
• Creating high-resolution terrain maps for coastal zone management based on the gridded DEM tiles.
• Assessing habitat suitability by integrating land and underwater elevation data.

Strengths

• High-resolution 1-meter gridded elevation data.
• Covers approximately 3251 square kilometers of coastline.
• Integrates topographic and bathymetric (ground, bathymetric point, submerged object) data classes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific Chesapeake Bay coastline project area.
