NOAA Shoreline Mapping for the Delaware River from Philadelphia to Trenton

NOAA's Shoreline Mapping Program provides a high-resolution vector shoreline for the Delaware River between Philadelphia and Trenton. The data is derived from imagery interpretation and structured using the Coastal Cartographic Object Attribute Source Table (C-COAST) attribution scheme. This dataset was last updated on March 13, 2026.

Use Cases

• Coastal change detection based on high-resolution shoreline vectors.
• GIS layer integration for regional planning based on the vector shoreline data.
• Hydrographic data translation and standardization based on the C-COAST attribution scheme.
• Baseline mapping for environmental studies based on the interpreted imagery.

Strengths

• Data is described as 'accurate high-resolution shoreline'.
• Shoreline is provided as both line and point vector shapefiles.
• Attribution follows a defined scheme (C-COAST) influenced by international standards.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is based on office interpretation of imagery, which may introduce interpretation bias.
