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!

- 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.
