A high-resolution vector shoreline dataset compiled from imagery for the Hogan Island to Khaz Bay region in Alaska. The data, created by the National Oceanic and Atmospheric Administration, is suitable for GIS layers and uses the NGS-developed C-COAST attribution scheme. The metadata was last updated on 2026-03 13.
Use Cases
- Coastal change analysis based on high-resolution shoreline vectors.
- GIS layer integration for mapping projects based on the C-COAST attribution scheme.
- Hydrographic data translation preparation based on the S-57 influenced data structure.
- Coastal habitat and infrastructure planning based on accurate shoreline delineation.
Strengths
- Data is described as providing an accurate high-resolution shoreline.
- Uses a specific attribution scheme (C-COAST) developed to conform various shoreline data sources.
- Metadata describes both line and point shapefiles.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
