NOAA Shoreline Mapping for New Orleans Lakefront Airport and Lake Pontchartrain

The National Oceanic and Atmospheric Administration's Shoreline Mapping Program provides a high-resolution vector shoreline for the New Orleans Lakefront Airport and Lake Pontchartrain area. The data is compiled from imagery and structured using the C-COAST attribution scheme for GIS compatibility. This dataset is a member of the NOAA InPort catalog and was last updated in March 2026.

Use Cases

• Update coastal GIS basemaps based on the high-resolution vector shoreline data.
• Analyze shoreline change near critical infrastructure like the New Orleans Lakefront Airport.
• Support nautical charting and hydrographic surveys using data structured for S-57 translation.
• Conduct coastal zone management and planning for the Lake Pontchartrain to ICW area.

Strengths

• Data is described as 'accurate high-resolution shoreline' compiled from imagery.
• Shoreline attribution follows the structured C-COAST scheme, influenced by the IHO S-57 standard.
• Dataset is maintained by the authoritative National Oceanic and Atmospheric Administration.

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 require conversion for GIS use.
