After Musing about creating an update to the One Month of Traffic map from November 2011 – I went  back into the data archives, and found the last full month I have August 2016.

So Above is a first look at the data, without context. the 2016 map the data set was huge – 4.6 million lines in the text file – 509mb in size, 2.5 times bigger then the 2011 Map. More vessels now carry AIS – including the ferries, which you can see fanning out in the middle of the map.

As part of this Update, I also have been documenting how I built it, in detail, which will become its own post. If you want to play now, I am giving away the point data above. you can download it here: http://halifaxshippingnews.ca/AugPoints.csv (.csv 115mb) the data includes Lat/Long, Date/time and ships MMSI.
