Coastal Mapping Program: High-Resolution Shoreline for Barataria Waterway, Louisiana

NOAA's National Ocean Service provides a high-resolution vector shoreline for the Barataria Waterway from Bayou des Oies to Bayou Cutler, Louisiana. The data is compiled from imagery and structured for GIS use, following the NGS-developed C-COAST attribution scheme. This dataset is part of the Coastal Mapping Program and was last updated in March 2026.

Use Cases

• Coastal change analysis based on high-resolution shoreline delineation
• GIS layer integration for habitat mapping based on vector shoreline data
• Hydrographic data translation based on attribution influenced by S-57 standards
• Coastal infrastructure planning based on accurate geographic information system layers

Strengths

• Data is described as providing an accurate high-resolution shoreline
• Attribution follows a defined scheme (C-COAST) developed by the National Geodetic Survey
• Source organization is the authoritative National Oceanic and Atmospheric Administration

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is based on office interpretation of imagery, which may introduce interpretation bias
