Vessel Traffic Data February2023
The Craft Tracking System (CTS) and Mariweb are AMSA’s vessel traffic databases. They collect vessel traffic data from a variety of sources, including terrestrial and satellite shipborne Automatic Identification System (AIS) data sources.
This dataset has been built from AIS data extracted from CTS, and it contains vessel traffic data for the month of February 2023. The dataset covers the extents of Australia’s Search and Rescue Region.
Each point within the dataset represents a vessel position report and is spatially and temporally defined by geographic coordinates and a Universal Time Coordinate (UTC) timestamp respectively.
Coordinate System: WGS1984
