A high-resolution vector shoreline dataset for the Sacramento River, California, from Sacramento to Colusa. The data was compiled by the National Oceanic and Atmospheric Administration (NOAA) from imagery and is attributed using the Coastal Cartographic Object Attribute Source Table (C-COAST) scheme. The metadata describes both line and point shapefiles suitable for GIS use.
Use Cases
- Coastal change detection and erosion analysis based on high-resolution shoreline vectors.
- GIS layer integration for habitat mapping or land-use planning based on the described shapefiles.
- Hydrological modeling and flood risk assessment based on the accurate river shoreline data.
- Cartographic production and nautical chart updating based on the C-COAST attribution scheme.
Strengths
- Data is described as 'accurate high-resolution shoreline' compiled from imagery.
- Shoreline attribution follows the structured C-COAST scheme, influenced by the S-57 standard.
- Data is provided by the authoritative National Oceanic and Atmospheric Administration (NOAA).
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.
- Available file formats are listed as PDF and HTML, which may not be the primary geospatial data formats.
