George Washington Birthplace Shoreline Positions from 2001 to 2023

Shoreline features collected between 2001 and Spring 2023 at George Washington Birthplace National Monument (GEWA) in Virginia. The data represent the mean high-water shoreline position, recorded by GPS/GNSS at intervals of at least one point every 10 meters. It was assembled by the Department of the Interior for the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program.

Use Cases

• Modeling coastal erosion rates based on repeated shoreline position surveys.
• Analyzing the impact of storms on beach morphology based on the high tide swash line data.
• Monitoring long-term shoreline change for conservation planning at the national monument.

Strengths

• Data collection spans over two decades, from 2001 to Spring 2023.
• High-resolution GPS recording with positions taken at least every 10 meters.
• Surveys cover ocean, inlet, and bay shorelines for a comprehensive coastal view.

Limitations

• Some surveys collected prior to 2003 lack FGDC-compliant metadata records.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
