Slide 4 of 17: We have used an INSPIRE compliant 1km grid

Slide 5 of 17: It’s so detailed that we need to zoom in to see that it’s really a grid.

Slide 6 of 17: 1km 1km To explain how we made a density map we need to zoom in even more.

Slide 7 of 17: 1km 1km Imagine these are ships crossing those grid cells at a given time.

Slide 8 of 17: 1km 1km 2 3 1 2 We count the number of ships crossing each of those cells

Slide 9 of 17: 1km 1km 2 3 1 2 Then we add a color gradation. The result is a shipping traffic density map.
