Lake Superior Topobathy Lidar Digital Elevation Model for Whitefish Point, MI

161.5 square kilometers of coastal topography and bathymetry for Eastern Lake Superior, collected via airborne lidar. The National Oceanic and Atmospheric Administration produced this tiled raster dataset covering the area from Whitefish Point to Bay Mills, Michigan. The data includes specific grounded land cover classes and falls partially within an EPA Area of Concern.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution elevation data.
• Assessing flood risk and storm surge impacts for shoreline communities.
• Creating bathymetric charts for navigation and habitat mapping in nearshore areas.
• Analyzing land cover change over time by comparing the classified ground points to other datasets.

Strengths

• Covers a defined project area of approximately 161.5 square kilometers.
• Data is processed into 23 standardized tiles of 5000m x 5000m for easier handling.
• Includes specific classified ground features (classes 2, 40, 43) relevant for terrain analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some analytical methods.
• The description metadata is limited; actual data resolution and accuracy require manual inspection.
