AIS
Data Sources
Analytic Process
100

Displays icon next to vessels that have recently changed static data.

History of Change

100

Will typically transit from one point to another, in the most efficient manner to preserve time and money.

Cargo and Tankers

100

Type of AIS source that detects vessels in close proximity to land.

Terrestrial

100

Detects vessel based off of radar or communication transmissions

Hawkeye 360

100

Function to review in SeaVision to identify vessel patterns of behavior, to include movement, waypoints, and speed.

History Trail

200

Displays icon next to vessel where there is an issue with the IMO or MMSI number.

Invalid Data

200

Will move at a higher rate of speed to an area, and then will slow down and make various types of passes over a point in the ocean.

Fishing vessels

200

The name of these devices will frequently change based on the battery life of their devices. 

Nets and Buoys

200

Provides high quality image, full motion video, and vessel associations.

Smartmast

200

Type of file that should be exported to review specific data points about a list of vessels, coordinates, etc.

CSV
300

Displays icon next to vessel that has been observed doing an impossible change in its position.

Anomalous Data

300

Operational area will be restricted to one specific port area, or various port areas around the world

Service vessels

300

Manipulating data to intentionally misrepresent the current position of a vessel.

Spoofing

300

Allows user to review IMO registration information for an assortment of items, to include vessels, owner, and operators.

Vessel Associations

300

SeaVision tool that allows user to not only review activity of vessel, but also other vessels it was interacting with during a specific period of time.

Time Machine

400

Displays historical and near-real time concentrations of AIS transmissions.

Heatmap 

400

Repeatable pattern of behavior each day, sometimes several times a day.

Passenger vessels

400

Calculation manually conducted to determine if an IMO number is valid.

Checksum

400
Provides evidence of illumination on the water, but is not effective in day light.

VIIRs

400
Characteristics of vessel data card that identifies potential safety or security concerns with a vessel.

Warnings

500

Uses machine learning AI to identify vessels involved in fishing and ship to ship activities.

Events

500

Difficult to predict, as there is no specific vessel type, and patterns will depend based on the specific mission of the vessel.

Research vessels
500

The first three numbers of an MMSI that is specifically associated with a country.

MID Code

500

Allows user to bring in external overlays and data files into SeaVision.

Import

500

Rather than focusing on a single assumption, we should objectively review the data to attempt to reduce this.
