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.

2011 AIS at 1 Minute Intervals for UTM Zone 15 and 16. (Note: Zone 17 portion of Great Lakes data is found in East Coast data) | Source Geospatial Form: vector digital data | Type of Source Media: online

Process Steps

Process Step 1

CC ID: 652583
Description:

1 Download all 2011 geodatabases for UTM zones 15 and 16 from https://marinecadastre.gov/AIS/default.aspx as well as the AIS Track Builder tool.

2 For all months in Zone 15 and 16 deleted data points from the Broadcast feature class falling outside the United States, Gulf of Mexico region UTM zones 15 and 16. Used Esri's World UTM Grid from ArcGIS online for reference.

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 for the tool was to break track lines using "Maximum Time and Distance", maximum time value = 30 and maximum distance value = 1. Also included both the Voyage and Vessel attributes. Ran Model for each UTM zone.

4 MERGE of all monthly track line feature classes for each of the UTM zones. Now have 2 feature classes representing total 2011 annual vessel traffic for each UTM Zone 15 and 16.

5 Removal of superfluous fields.

6 Create model to create max draught in meters field for annual feature class, calculate statistics to find the maximum draft value, create new field "maxDraught" in this statistics result intermediate feature class, add values to this new field using field calculator in 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 web mercator.

9 MERGE all three UTM zone's annual track lines into one feature class to create 2011 annual Great Lakes track lines feature class.

10 Repair geometry for the merged regional file.

11 Add spatial index.
