Title: Nationwide Automatic Identification System 2012
Short Name: AISDataHandler2012Metadata
Status: Completed
Publication Date: 2014-12
Abstract:

The 2012 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.

Purpose:

To support coastal planning and other activities pursuant to the Coastal Zone Management Act, Energy Policy Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.

Activity Log 3

CC ID: 717192
Activity Date/Time: 2018-02-08
Description:

Partial upload of Positional Accuracy fields only.

Data Quality

Accuracy:

The attributes in this dataset are believed to be accurate.

Horizontal Positional Accuracy:

Positional accuracy reflects the specifications and methods of the original data producer and has not been modified for the generation of this product.

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.

Conceptual Consistency:

Point data. No topology between points.

Process Steps

Process Step 1

CC ID: 650881
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.
