Abstract

AIS vessel transit data for 2015 processed by ABPmer on behalf of the MMO, using data supplied by the Maritime and Coastguard Agency (MCA), following a methodology previously developed by ABPmer under MMO project number 1066, entitled 'Mapping UK Shipping Density and Routes from AIS Open Source Data and Methods'. This feature class contains vessel tracks or 'transits' derived from AIS-A and AIS-B positional data provided by the Maritime and Coastguard Agency (MCA). The transit lines represent the UK AIS-A and AIS-B 2015 data as continuous vessel tracks, generated from sequential vessel positions. This was achieved by plotting vessel positional data using MMSI identification numbers. The transit lines provide all ship type groups (STG), including the 'unknown' vessel type classifications.This dataset contains the anonymised transit line data used to create the 2015 UK shipping density grid.Ship type groups (STG):0 - Unknown Vessels1 - Non-Port service craft2 - Port service craft3 - Vessels engaged in dredging or underwater operations4 - High Speed Craft5 - Military or Law enforcement6 - Passenger7 - Cargo8 - Tankers9 - Fishing vessels10 - Recreational vessels

Lineage

The MCA supplied 12 weeks (the first 7 days of each month of 2015) of type A and type B AIS data on behalf of the MMO to ABPmer for processing and production of the vessel transit lines and vessel density grid. AIS-A is carried by international voyaging ships with gross tonnage (GT) of 300 or more tonnes, and all passenger ships regardless of size. The data contained message types 1, 2 and 3 (position reports). AIS-B is carried by smaller vessels and is aimed at the leisure and fishing sector. This data contained message types 18 and 19 (position reports). The AIS data was decoded and simplified to identify track or 'transit' lines which were then plotted using ArcGIS. For full methodology including processing techniques and data outputs please see the MMO1066 report Mapping UK Shipping Density and Routes technical annex. An overview of the process can be found in Figure 3, pg 12. The Ship Type Group (STG) vessel codes are as follows: 0 - Unknown Vessels 1 - Non-Port service craft 2 - Port service craft 3 - Vessels engaged in dredging or underwater operations 4 - High Speed Craft 5 - Military or Law enforcement 6 - Passenger 7 - Cargo 8 - Tankers 9 - Fishing vessels 10 - Recreational vessels AIS Transit Line data for 2015 attribution are as follows: Transit_ID: Vessel transit ID used in data processing DateTimeStart: Time and date at start of vessel transit DateTimeFinish: Time and date at end of vessel transit ShipTypeGroup - Ship Type Group (STG) classification ShipLength - Ship Length (m) ShipWidth - Ship Width (m) Draughtx10 - Ship Draught x10 (m x 10) VoyageDataSource - Voyage Data Source TransitLength - Transit Length (m) PositionDensity - Position density code TransitEndReason - Transit End Reason code AISType - AIS Type (A - 1,2,3 or B - 18 or 19) Month - Month data recorded Datestart: Date at start of vessel transit Datefinish: Date at end of vessel transit Timestart: Time at start of vessel transit Timefinish: Time at end of vessel transit VTC classification (Stage 2 of AIS Data Processing) and Lloyds List vessel type (Stage 3 of AIS Data Processing) were not carried out on the 2015 AIS dataset.
