From the Baltic Sea to South AfricaAIS data for Baltic Scope
Manuel FriasHELCOM SecretariatBaltic Scope partner meetingSzczecin, Poland June 2016
We have produced shipping traffic density maps
What is a
density map?
We have used an INSPIRE compliant 1km grid
It’s so detailed that we need to zoom in to see that it’s really a grid.
1km
1km
To explain how we made a density map we need to zoom in even more.
1km

Imagine these are ships crossing those grid cells at a given time.

We count the number of ships crossing each of those cells

Then we add a color gradation. The result is a shipping traffic density map.

It looks simple, but it’s aVERY time-consuming process.

How big is one year of AIS data?
2013 contains
1,3 BILLION rows
If we printed them we would need
30 MILLIONA4 pages
If we put them one after anotherit’d reach South Africa
