Historical Shoreline of Port Valdez Oil Terminal, Alaska

A high-resolution historical shoreline dataset for the Port Valdez Oil Terminal in Alaska, derived from NOAA National Ocean Service maps. The data were automated for use as a GIS data layer and attributed using the NGS-developed C-COAST scheme to align with international hydrographic standards. This resource is part of a larger NOAA data collection.

Use Cases

• Coastal change analysis based on historical shoreline maps.
• GIS layer creation for environmental impact studies around the oil terminal.
• Data integration and translation projects based on the C-COAST attribution scheme.
• Historical baseline mapping for coastal zone management.

Strengths

• Data were automated to provide an accurate high-resolution historical shoreline.
• Attribution uses the C-COAST scheme, influenced by the International Hydrographic Organization's S-57 standard.
• Derived from shoreline maps produced by NOAA National Ocean Service and its predecessor agencies.

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 GIS analysis.
