NOAA's National Geodetic Survey provides an accurate high-resolution vector shoreline for Western St. Lawrence Island, Alaska, compiled from imagery. The data uses the NGS-developed C-COAST attribution scheme, influenced by the International Hydrographic Organization's S-57 standard for interoperability. This resource is a member of the NOAA InPort catalog item 39808.
Use Cases
- Coastal change detection based on high-resolution shoreline vectors.
- GIS data layer integration for coastal mapping projects based on the vector shapefiles.
- Attribution analysis for hydrographic data translation based on the C-COAST scheme.
- Baseline creation for coastal habitat or erosion studies based on the interpreted shoreline.
Strengths
- Data is described as 'accurate high-resolution shoreline'.
- Shoreline is compiled from imagery, suggesting a remote sensing source.
- Attribution follows a defined scheme (C-COAST) for standardization.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- File formats are listed as PDF and HTML, which may not be the primary geospatial data formats.
