Footoscope provides a perspective on the morphology and tactics of a football team according to raw data on its passing game (e.g. passes between players, positions of the players when receiving the ball, playing time) transformed into indicators (e.g. “betweenness”) and visualizations (e.g. flows in the passing game, orientation of the propagation of the ball, layout of the team).
