Abstract:This layer an aggregation of annual vessel traffic from 2020.  The Vessel Tracks have been derived from data sourced from the Australian Maritime Safety Authority. Converted into FGDB Time Field generated using Convert Time field geoprocessing Tool dd/MM/yyyy hh:mm:ss tt Unique Vessel ID generated by Field Calculator Type=Long, Numeric no decimal places Field Calc: ID=!CRAFT_ID!/100AIS Tracks build from MarineCadastre Trackbuilder Pro, downloadable from https://marinecadastre.gov/tools/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 year 2020. 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.Source data:© Commonwealth of Australia (Australian Maritime Safety Authority) 2020Further information and data download available from AMSA:https://www.operations.amsa.gov.au/Spatial/DataServices/DigitalData
