Shoreline Data Rescue Project: Historical Shoreline of Barataria Bay, Louisiana

Barataria Bay, Louisiana, is the focus of this high-resolution historical shoreline dataset. The data were automated from NOAA National Ocean Service maps, based on imagery interpretation and field surveys, and structured using the NGS C-COAST attribution scheme to facilitate translation into the S-57 standard.

Use Cases

• Analyze historical shoreline change based on the high-resolution automated shoreline data.
• Integrate coastal features into GIS systems based on the C-COAST attribution scheme.
• Translate shoreline data into S-57 hydrographic standard formats based on the described attribution influence.

Strengths

• Data are described as providing an accurate high-resolution historical shoreline.
• Shoreline maps were produced by the NOAA National Ocean Service and its predecessor agencies.
• Attribution scheme (C-COAST) was developed to conform various shoreline data sources into one catalog.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats are limited to PDF and HTML, which may not be ideal for direct geospatial analysis.
