Historical Shoreline Data for the Delaware River, New Jersey

A high-resolution historical shoreline dataset for the Delaware River in New Jersey, automated for GIS use. The data were produced by the NOAA National Ocean Service and its predecessors, based on interpretation of imagery and field surveys. The attribution follows the NGS-developed C-COAST scheme, influenced by the S-57 standard for hydrographic data.

Use Cases

• Analyzing shoreline change over time based on the historical mapping methods described.
• Creating coastal base maps for GIS applications based on the high-resolution shoreline data.
• Translating shoreline data into S-57 hydrographic formats based on the C-COAST attribution scheme.
• Studying coastal erosion or accretion in the Delaware River region based on the historical data source.

Strengths

• Data is described as high-resolution and accurate for GIS use.
• Shoreline maps were produced by NOAA National Ocean Service and its predecessor agencies.
• Attribution scheme (C-COAST) was developed to conform data from various sources.

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.
• Data formats are limited to PDF and HTML, which may not be ideal for direct geospatial analysis.
