* » Abstract

Automatic Identification Systems (AIS) are a navigation safety device that transmits and monitors the location and characteristics of many vessels in U.S. and international waters in real-time. In the U.S. the Coast Guard and industry collect AIS data, which can also be used for a variety of coastal planning purposes. NOAA and BOEM have worked jointly to re-task and make available some of the most important records from the U.S. Coast Guard's national network of AIS receivers. Information such as location, time, ship type, length, width, and draft have been extracted from the raw data and prepared as track lines for analyses in desktop GIS software.
* Purpose

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

Process Steps

Process Step Number 1
» Description

1. Download all 2013 geodatabases for UTM zones 15, 16, 17, and 18 from https://marinecadastre.gov/ais/, as well as the AIS Track Builder tool.

2. For all months in Zone 15, 16, 17, and 18 clip data points from the Broadcast feature class to retain only those in the Great Lakes region.

3. Create model for each of the UTM zones to run the track builder tool on each of the monthly Broadcast feature classes. Settings used within the tool include: break track lines using "Maximum Time and Distance"; maximum time value = 30; and maximum distance value = 1. Also include both the Voyage and Vessel attributes. Run Model for each UTM zone.

4. MERGE all monthly track line feature classes per UTM zone. Four feature classes representing total 2013 annual vessel traffic for UTM Zones 15-18 are the end product.

5. Remove superfluous fields.

6. Create model to generate max draught field (in meters) for annual feature class as follows: a) calculate statistics to find the maximum draft value; b) create new field "maxDraught" in the intermediate statistics feature class; c) calculate values for this new field using the field calculator expression: [max draught statistic] * 0.1. This calculation converts the draught values form 1/10th meter units to meter units. Join this field to the annual feature class based on the MMSI field.

7. REPAIR GEOMETRY for each of the annual track line feature classes for each UTM Zone.

8. REPROJECT all three UTM zone's annual tracklines into NAD83.

9. MERGE all three UTM zone's annual track lines into one feature class to create 2013 annual Great Lakes track lines feature class.

10. REPAIR GEOMETRY for the merged regional file.
