U.S. Vessel Traffic Data for 2009 from Automatic Identification System

204 File Geodatabases contain vessel traffic data for U.S. coastal waters in 2009, organized by month and UTM zone. Each geodatabase includes a point feature class for position reports and tables for voyage, vessel, and base station information. The data was collected by the National Oceanic and Atmospheric Administration for planning purposes.

Use Cases

• Model vessel movement patterns based on one-minute-interval position reports.
• Analyze voyage-specific characteristics based on static data linked to position reports.
• Study vessel-specific attributes like identity and type across different traffic zones.
• Map data collection infrastructure based on the listed base stations per UTM zone.

Strengths

• Data is structured into 204 self-contained geodatabases for specific months and UTM zones.
• Includes relationship classes linking position reports to vessel and voyage tables.
• Position reports are pre-filtered to a consistent one-minute time step.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from 2009; freshness should be verified for contemporary applications.
