The 2014 United States Automatic Identification System Database contains vessel traffic data for planning purposes within the U.S. coastal waters. The database is composed of 216 self-contained File Geodatabases (FGDB). Each FGDB represents one month of data for a single UTM zone. The UTM zones represented cover the entire United States and include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 14, 15, 16, 17, 18, 19, and 20. Each FGDB consists of one feature class, four tables, and two relationship classes. The Broadcast point feature class contains the position reports, which have been pre-filtered to a one-minute time step. The Voyage table contains elements of the static data reports that are updated for each ship voyage. The Vessel table contains elements of the static data reports that are specific to a particular vessel. The BaseStations table lists the base stations collecting data for a particular month/UTM zone. The AttributeUnits table contains a list of units for each of the attribute fields in the Broadcast, Voyage, and Vessel tables. The BroadcastHasVessel relationship class relates the broadcast points to the vessel table records. The BroadcastHasVoyage relationship class relates the broadcast points to the voyage table records. The Broadcast feature class and the Voyage, Vessel, and BaseStation tables each contain the UTM zone, year, and month in the file name.

Each FGDB consists of one feature class, four tables, and two relationship classes. The Broadcast point feature class contains the position reports, which have been pre-filtered to a one-minute time step. The Voyage table contains elements of the static data reports that are updated for each ship voyage.

| Description: |
Partial upload of Positional Accuracy fields only. |
Data Quality
| Horizontal Positional Accuracy: |
Compiled to meet 10 meters horizontal accuracy at 95% confidence level |
|---|---|
| Completeness Report: |
Points were filtered to a one-minute time step before publishing the data. Vessel identification data was altered prior to distribution by encoding the MMSI numbers and removing the vessel name, IMO, and call sign information. Raw AIS file sizes for November and December were smaller than prior months in 2014, resulting in lower AIS record counts for these months. |
| Conceptual Consistency: |
These data are logically consistent |

| Source Contribution: |
Data received for the entire United States in a total of 447 daily files of AIS messages for the months of January through December. In many cases there were multiple raw files for each day. | Type of Source Media: disc |
Process Steps
Process Step 1
| Description: |
The data was divided spatially by UTM zone and aggregated temporally to monthly datasets using AISParser. The data was then converted to FGDB using the AIS data model created for this project and a custom script which implements AISParser and ArcObjects. |
