Cape Cod National Seashore Shoreline Positions from GPS Surveys, 1994-2025

A series of mean high-water shorelines collected at Cape Cod National Seashore between Fall 1994 and Spring 2025. The data were assembled by the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. Shoreline positions were recorded by driving or walking along the high tide swash line, with GPS configured to log at least one position 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 conservation planning at Cape Cod National Seashore.

Strengths

• Over 30 years of temporal coverage from 1994 to 2025.
• High-resolution GPS data collection with positions recorded at least every 10 meters.
• Data collected under a formal monitoring program for the Northeast Coastal & Barrier Network.

Limitations

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