NOAA Shoreline Mapping Program: High-Resolution Vector Shoreline of Battery Point, Alaska

Battery Point in Kelgaya Bay, Alaska, is covered by a high-resolution vector shoreline dataset compiled from imagery by the National Oceanic and Atmospheric Administration. The data, last updated in March 2026, includes line and point shapefiles attributed using the NGS-developed C-COAST scheme for GIS compatibility. This dataset is part of a larger NOAA shoreline mapping program.

Use Cases

• Conducting coastal erosion studies based on the high-resolution shoreline vector data.
• Integrating shoreline layers into GIS for coastal planning and management.
• Analyzing shoreline change over time by comparing this dataset with other NOAA shoreline surveys.
• Creating base maps for nautical charts or environmental assessments based on the attributed vector data.

Strengths

• Data is described as providing an accurate high-resolution shoreline.
• Shoreline attribution uses the C-COAST scheme, influenced by the international S-57 standard for hydrographic data.
• Dataset is part of a formal NOAA program, suggesting a degree of institutional curation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is available only in PDF and HTML formats, which may limit direct GIS use.
