NOAA Shoreline Data Rescue Project for Indian River Bay, Delaware

NOAA's National Ocean Service provides a high-resolution historical shoreline for Indian River Bay, Delaware, derived from office interpretation of imagery and field surveys. The data uses the C-COAST attribution scheme, influenced by the International Hydrographic Organization's S-57 standard for compatibility. This resource is part of a larger NOAA data collection and was last updated in March 2026.

Use Cases

• Analyze historical shoreline change based on high-resolution geospatial data.
• Integrate shoreline layers into coastal GIS models based on the C-COAST attribution scheme.
• Study coastal erosion or accretion patterns in Delaware's Indian River Bay.
• Translate shoreline data for hydrographic applications based on S-57 standard influence.

Strengths

• Data is derived from NOAA National Ocean Service shoreline maps, an authoritative source.
• Shoreline is described as high-resolution and accurate, suitable for GIS.
• Attribution uses the structured C-COAST scheme for consistency.

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 may reflect geographic and temporal bias inherent to the source imagery and surveys.
