This lecture presents a 3D graphic model of the Ecublens moraine, divided into 92 zones assigned to each student for the creation of individual graphical representations. The students developed a graphic charter defining symbols and representation rules. The responsibility for teaching lies with Paule Soubeyrand and assistants Emy Amstein, Chloé Daguillon, Adrien Gilliand, Claire Logoz, Julia Magnin, Carla Scharff-Hansen, Michael Di Dio, Januga Kesavan, and Lea Bredou.
