Vessel Density Grid 2015
AIS_Density_2015
Vessel_Density_Grid_2015.shp
This dataset contains the average weekly shipping density for the whole of the UK at a 2km grid resolution. For 2015, AIS datasets were sampled from the first seven days of each month, commencing with January,at monthly intervals.The total value for all 12weeks was divided by 12to determine the weekly average, therefore decimal values may occur for certain cells. The weekly average was also multiplied by 52 to provide the estimated annual average.

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 â??transitâ?? 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 The field headings in the attribute table are as follows: CELL_ID â?? ID of grid cell Avg_STG_0 - Weekly average number of transits of Unknown Vessels Avg_STG_1 - Weekly average number of transits of Non-Port service craft Avg_STG_2 - Weekly average number of transits of Port service craft Avg_STG_3 - Weekly average number of transits of Vessels engaged in dredging or underwater operations Avg_STG_4 - Weekly average number of transits of High Speed Craft Avg_STG_5 - Weekly average number of transits of Military or Law enforcement vessels Avg_STG_6 - Weekly average number of transits of Passenger vessels Avg_STG_7 - Weekly average number of transits of Cargo vessels Avg_STG_8 - Weekly average number of transits of Tankers Avg_STG_9 - Weekly average number of transits of Fishing vessels Avg_STG_10 - Weekly average number of transits of Recreational vessels Avg_Total_STG - Weekly average number of all vessel transits Weekly_Avg_STG_Total - Weekly average number of all vessel transits Yearly_Avg_STG_Total - Estimated annual density of all vessel transits
