Title

MMO1066 Vessel density grid 2012

Abstract

This dataset contains the average weekly shipping density for the whole of the UK at a 2km² grid resolution. For 2012, AIS datasets were sampled from the first seven days of the month, commencing with January, at two-month intervals. The total value for all 6 weeks sampled was then divided by 6 to determine the weekly average (note that this process has resulted in decimal values occurring for certain cells). The weekly average was then multiplied by 52 to provide the estimated annual average. The field headings in the attribute table 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 Week_Ave - Weekly Average Density Annual_Ave - Estimated annual density

Quality and validity

Lineage

The MCA supplied type A and type B AIS data on behalf of 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 vessel type details were verified against data supplied by Lloyds List Intelligence. For full methodology including processing techniques and data outputs please see the MMO1066 reports Mapping UK Shipping Density and Routes from AIS and Mapping UK Shipping Density and Routes technical annex.
