Abstract
This dataset contains the anonymised transit line data used to create the 2014 UK shipping density grid.The MCA were currently mid-way through amodernisation programme which involvedupdating the current network. As a result the MCA had AIS base stations on both the old (Legacy) and new (FCG) networks. This dataset used the AIS data from both the Legacy (Jan-Apr) and FCG (May-Dec) systems to create a finalised 2014 dataset.

Lineage
The MCA supplied type A and type B AIS data on behalf of the MMO. 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, 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.
The Ship Type Group 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

Caveats:
Lloyds List categorises âRoll On Roll Offâ (RORO) vessel types as Cargo vessels. As part of the process to create AIS tracks, verification against Lloyds List has meant that some passenger ferry vessels classified as RORO, have been categorised as Cargo. The MMO corrected these attributes after identification of vessels and cross referencing of vessel types. For more information on Lloyds List types and categories, please see https://help.marinetraffic.com/hc/en-us/articles/205579997-What-is-the-significance-of-the-AIS-SHIPTYPE-number-
