Quality and validity

Lineage

The MCA supplied type A and type B AIS data to the MMO. AIS-A is carried by vessels with gross tonnage (GT) of 300 or more tonnes, and all passenger ships regardless of size, as required by IMO (SOLAS) regulation. The data contained message types 1, 2, 3 and 5 . AIS-B is carried by smaller vessels and is aimed at the leisure and fishing sector. This data contained message types 18, 19 and 24 . The AIS data was decoded and simplified to identify track lines which were then plotted using GIS. 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. Weekly AIS Transit Line data for [year] attribution as follows: Fields from Transit table data from Stage 2 of AIS Data Processing: ShipTypeGr - Ship Type Group, ShipLength - Ship Length, ShipWidth - Ship Width, Draughtx10 - Ship Draught x10, VoyageData - Voyage Data Source, TransLen - Transit Length, PosDen - PositionDensity, TransEndRe, - Transit End Reason, AISType - AIS Type Fields from Stage 4 of AIS Data Processing (following Lloyds List Validation) that have been truncated: LloydsVess - Lloyds Vessel Type, Group_Corr - Group Correction, CorrectedG - Corrected Group, Draught_Cor - Draught Correction, CorrectedD - Corrected Draught.
