Chesapeake Bay, Maryland, is covered by two lidar datasets (MD1902 and MD1903) collected by NV5 Geospatial in November 2019. The data includes classified point clouds and derived 1-meter resolution digital elevation models (DEMs) covering approximately 260 and 273 square kilometers respectively. The National Oceanic and Atmospheric Administration (NOAA) processed the lidar data into GeoTIFF format.
Use Cases
- Model coastal erosion and sediment transport based on detailed elevation and bathymetric data.
- Analyze submerged topography and water column features for marine habitat classification.
- Generate high-resolution terrain models for flood inundation and storm surge simulations.
- Assess changes in shoreline and nearshore bathymetry using classified ground and water surface points.
Strengths
- Data includes detailed point classifications (e.g., ground, water surface, submerged feature) following ASPRS standards.
- DEMs have a high spatial resolution of 1 meter per pixel.
- Project areas cover specific, quantified regions (approximately 260.195 and 273.518 square kilometers).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
