NOAA Shoreline Data Rescue Project for Monomoy Island to Chatham Harbor, Massachusetts

NOAA's high-resolution historical shoreline data for Monomoy Island to Chatham Harbor, Massachusetts, automated for GIS use. The data are derived from shoreline maps produced by the NOAA National Ocean Service based on imagery interpretation and field surveys. Attribution follows the NGS-developed C-COAST scheme, influenced by the S-57 standard for hydrographic data.

Use Cases

• Analyze historical shoreline change and coastal erosion based on the high-resolution historical shoreline data.
• Create GIS basemaps for coastal zone management based on the automated geographic information system data layer.
• Study coastal geomorphology and sediment transport patterns based on the interpreted imagery and field survey data.
• Translate shoreline data into hydrographic charting standards based on the S-57-influenced C-COAST attribution scheme.

Strengths

• Data is derived from authoritative NOAA National Ocean Service shoreline maps.
• Shoreline is described as high-resolution and accurate, suitable for GIS.
• Attribution scheme (C-COAST) was developed to conform various data sources and facilitate translation to the S-57 standard.

Limitations

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