Historical Shoreline Data for Big Lagoon to Pensacola Bay, AL and FL

A high-resolution historical shoreline dataset for the Big Lagoon to Pensacola Bay area in Alabama and Florida, derived from NOAA National Ocean Service maps. The data were automated to provide an accurate GIS data layer based on office interpretation of imagery and/or field surveys. The attribution follows the NGS-developed C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.

Use Cases

• Analyze coastal erosion or accretion rates based on the historical shoreline data.
• Create baseline GIS layers for coastal zone management based on the high-resolution shoreline.
• Validate or translate shoreline data into S-57 hydrographic formats based on the C-COAST attribution scheme.

Strengths

• Data is described as high-resolution and accurate for GIS use.
• Shoreline is derived from authoritative NOAA National Ocean Service maps.
• Attribution scheme is designed for compatibility with the S-57 hydrographic standard.

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.
