A high-resolution vector shoreline dataset compiled from imagery for the Louisiana coast from Morgan City to Forked Island. The data is provided by the National Oceanic and Atmospheric Administration and was last updated in March 2026. It includes line and point shapefiles with attribution based on the Coastal Cartographic Object Attribute Source Table (C-COAST) scheme.
Use Cases
- Conducting coastal erosion studies based on the high-resolution shoreline data.
- Integrating shoreline layers into geographic information systems (GIS) for regional planning.
- Analyzing shoreline change over time by comparing this vector data with historical datasets.
- Translating coastal features into S-57 hydrographic data format based on the C-COAST attribution scheme.
Strengths
- Data is described as high-resolution and accurate for the specified coastal region.
- Shoreline features are provided in both line and point vector formats.
- Attribution follows a structured scheme (C-COAST) designed for translation to international standards.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Available file formats are PDF and HTML, which may require conversion for direct GIS use.
