Historical Shoreline of the Delaware River, PA and NJ, 1935

NOAA National Ocean Service provides a high-resolution historical shoreline data layer for the Delaware River, derived from office interpretation of imagery and field surveys. The data uses the NGS C-COAST attribution scheme, influenced by the International Hydrographic Organization's S-57 standard. This resource is a member of the NOAA InPort catalog under item 39808.

Use Cases

• Analyze historical shoreline change and erosion based on the high-resolution GIS data layer.
• Integrate historical coastal features into modern GIS systems based on the C-COAST attribution scheme.
• Model coastal zone dynamics for the Delaware River based on the derived shoreline maps.
• Translate shoreline data into S-57 compliant formats for hydrographic applications based on the described attribution influence.

Strengths

• Data is described as providing an accurate high-resolution historical shoreline suitable for GIS.
• Shoreline maps were produced by the NOAA National Ocean Service and its predecessor agencies.
