Coastal Maine Topobathymetric Lidar Elevation Model, 2022-2023

Lidar data collected between October 2022 and December 2023 in 120 missions by NV5 for NOAA. The processed data were transformed to geoidal heights and used to create 1-meter resolution topobathymetric digital elevation models (DEMs) in Cloud Optimized GeoTIFF format. The dataset covers coastal Maine and was produced by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling coastal erosion and flooding based on high-resolution elevation and bathymetry data.
• Analyzing seafloor topography and nearshore habitats based on the integrated topobathymetric model.
• Creating base maps for coastal infrastructure planning based on the 1-meter resolution DEM.
• Studying sediment transport and coastal processes based on the detailed elevation surface.

Strengths

• Data collection spanned over a year with 120 separate missions, suggesting thorough spatial coverage.
• Final products have a 1-meter pixel resolution, indicating high spatial detail.
• Data were processed to a standard geoidal datum (Geoid18) for consistent vertical referencing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total file size are unknown, which may limit suitability assessment.
