The document discusses shipping traffic density maps created from Automatic Identification System (AIS) data collected in the Baltic Sea region by the Baltic Scope project. It explains that density maps were created by counting the number of ships crossing 1km grid cells over a given time period and applying a color gradient to represent traffic density. One year of AIS data contains over 1.3 billion rows of data, which if printed would require 30 million pages of paper and stretch from the Baltic Sea to South Africa if placed end to end. The maps provide visualizations of shipping traffic densities in the Baltic Sea region from 2005 to 2014 broken down by vessel type.

From the Baltic Sea to South Africa - Shipping traffic density maps to Baltic Scope
- 1. From the Baltic Sea to South Africa AIS data for Baltic Scope Manuel Frias HELCOM Secretariat Baltic Scope partner meeting Szczecin, Poland June 2016
- 2. We have produced shipping traffic density maps
- 3. What is a density map?
- 4. We have used an INSPIRE compliant 1km grid
- 5. It’s so detailed that we need to zoom in to see that it’s really a grid.
- 6. 1km 1km To explain how we made a density map we need to zoom in even more.
- 7. 1km 1km Imagine these are ships crossing those grid cells at a given time.
- 8. 1km 1km 1 2 3 2 We count the number of ships crossing each of those cells
- 9. 1km 1km Then we add a color gradation.The result is a shipping traffic density map. 2 32 1
- 10. 1km 1km It looks simple, but it’s a VERY time-consuming process. 1 2 2 3
- 11. How big is one year of AIS data?
- 12. 2013 contains 1,3 BILLION rows
- 13. If we printed them we would need 30 MILLION A4 pages
- 14. If we put them one after another it’d reach South Africa
- 15. 13 2014 Passenger Fishing Cargo Tanker We have provided maps…
- 16. 2005 06 07 08 09 10 11 12 13 2014 Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown Cargo Tanker Container Passenger Service Fishing Vehicle C./ RoRo Cargo Other Unknown And now we can provide more…
- 17. So if you want more just tell us!
Editor's Notes
- Before defining a density map, we should say that we have used a INSPIRE compliant 1km grid because we wanted: As much detail as possible We wanted to use a standard that can be use for other HELCOM maps and thus compare results This grid is so detailed that we cannot even see the actual grid. But if we zoom…
- …we can see that it REALLY is very detailed!
- If we zoom more we can see an example of four cells to explain what a density map is: Imagine these lines are ship trips. A density map is the sum of those trips for every cell in the grid. So for us thsi values show how intense in the shipping traffic in the Baltic at a given time.
