Historical AIS Data Services
Historical AIS data is a valuable data source used for vessel traffic analysis, port calling information, asset tracking, risk assessment, accident investigation, etc. The data is also used for analysing the vessels movements on a global scale, potential trends in the shipping market or vessel behaviour patterns for potential prosecution of illegal actions.

VESSEL MOVEMENT REPORTS
Based on historical AIS data collected by terrestrial AIS stations since 2009, this service
provides data on the positions of thousands of ships around the world.
The AIS position reports are performed for:
- one or more vessels for a given period of time (on a predefined list of MMSI or IMO numbers)
- all vessel movements in a particular port or area (defined by geographical coordinates)
In most cases, typical time resolution of a vessel movement report is 5-minutes or 1-hour (time resolution is the time between two sequential position records of each vessel) depending on the customer needs. For more detailed analysis, when time resolution should be as small as possible, raw NMEA data is used to perform the movement report.
Data included in a standard vessel movement report:
- DATE / TIME timestamp of the position report
- MMSI – vessel's MMSI number
- IMO – vessel's IMO number
- NAME – vessel's name
- LATITUDE
- LONGITUDE
- COURSE – course over ground (degrees)
- SPEED – speed over ground (knots)
- HEADING – heading of the vessel's hull (in degrees)
- NAVSTAT – navigational status (according to AIS specification)
- CALLSIGN – vessel's call sign
- DIMENSIONS – length and beam of the vessel
- DRAUGHT – draught of the vessel at time of the position record
- DESTINATION – port of call
- ETA – estimated time of arrival
- AIS TYPE – vessel's type according to AIS specification
VIDEO SIMULATION
This service uses raw AIS data to create a video simulation of the vessels' movements on a digital map. This service is ideal to:
- investigate an accident
- analyse vessel behaviour patterns for potential prosecution of illegal actions, such as illegal ballast water exchange or illegal bunkering.
Data output:
- Raw timestamped NMEA data
- Decoded data
- Video simulation (AVI file)
TRAFFIC DENSITY ANALYSIS
Based on historical AIS data, this service provides vessel traffic density analysis in critical areas. The density analysis is performed for particular area and selection criteria by ship type, size, year of built, etc. This service is ideal if you are looking for density reports that enable:
- risk assessment and increasing of the efficiency of port services
- analysis into shipping traffic and trend patterns
Data output:
- Traffic density image
- Georeferenced KML file
- Entire AIS data set used to perform the analysis
