U.S. Transportation Network Features from USGS National Map

The USGS National Transportation Dataset (NTD) contains vector data for roads, railroads, trails, airports, and waterways across the United States. It is derived from U.S. Census Bureau TIGER/Line data supplemented with HERE road data and supports mapping and GIS analysis. The data includes feature names, route designators, classifications, and locations.

Use Cases

• Analyze road classification and name attributes for traffic safety or congestion studies.
• Map airport and airstrip locations alongside road networks for disaster planning and emergency response logistics.
• Combine trail and railway features with other geospatial themes like hydrography to create general reference base maps.
• Use the transportation feature data for geographic information system technology analysis in commerce and logistics.

Strengths

• Data is sourced from authoritative public sources like the U.S. Census Bureau and HERE.
• Covers a comprehensive set of transportation feature types including roads, railroads, trails, airports, and waterways.
• The dataset was last updated in January 2026, indicating recent maintenance.

Limitations

• The specific row count, column structure, and data size are unknown, limiting precise analytical planning.
• Data is provided in XML format, which may require conversion for use in common GIS or analysis tools.
