Shoreline Data Rescue Project: Historical Shoreline for Morgan Harbor, Louisiana

A high-resolution historical shoreline dataset for Morgan Harbor, Louisiana, automated for use as a GIS data layer. The data are derived from shoreline maps produced by the NOAA National Ocean Service and its predecessor agencies, based on imagery interpretation and field surveys. The attribution follows the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.

Use Cases

• Historical shoreline change analysis based on high-resolution historical shoreline data.
• GIS layer creation for coastal management planning based on the described geospatial data.
• Validation of modern shoreline models using historical reference data mentioned in the description.
• Coastal cartographic object attribution study based on the C-COAST scheme.

Strengths

• Data are described as high-resolution and accurate for GIS use.
• Shoreline maps were produced by the authoritative NOAA National Ocean Service.
• Attribution follows a structured scheme (C-COAST) influenced by an international standard (S-57).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Primary file formats are PDF and HTML, which may require extraction for direct geospatial analysis.
