Temporal variation of vessel activity was also discussed. Additional uses of AIS data were addressed and included risk mapping for invasive non-native species, fisheries, and general statistics. Vessel tracks showed variation in vessel routes, especially around island groups. Density mapping, derived from both point and vessel track data, proved highly informative but was unable to address all aspects of the data. The dataset was broken down by sector into meaningful and usable data packets which could also be analysed over time. Tools used included density mapping, vessel tracks, interpolations of vessel dimensions, and ship type analysis. Over 730,000 data points of AIS information for 2013 from around Shetland were processed, analysed, and mapped. Shelmerdine demonstrates a procedure for the processing, analysing, and visualisation of AIS data with example outputs and their potential uses. analytically model the AIS Self-Organized Time Division Multiple Access (SOTDMA) traffic pattern at the satellite and investigate the realistic behavior of SOTDMA via simulations. The technical characteristics behind the AIS system are published in Recommendation ITU-R M.1371-5.
