Sagamore Hill Shoreline Position Data from 2011 to 2024

Shoreline features collected between Fall 2011 and Fall 2024 at Sagamore Hill National Historic Site. The data represent a series of mean high-water shorelines assembled for the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. Surveys were conducted by driving or walking along the high tide swash line, with GPS/GNSS receivers recording positions at least every 10 meters.

Use Cases

• Modeling coastal erosion rates based on repeated shoreline position measurements.
• Analyzing the impact of storms on beach morphology based on the high tide swash line data.
• Monitoring long-term shoreline change for coastal management based on the 13-year time series.

Strengths

• Data collection spans 13 years from Fall 2011 to Fall 2024, providing a multi-year time series.
• GPS/GNSS positions were recorded at a high spatial frequency of at least one point every 10 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Some surveys collected prior to 2003 do not contain FGDC-compliant metadata records.
• Row count is unknown, which may limit suitability assessment.
