We developed a new method to clarify the local characteristics of football games using a dominant landscape. The idea is founded on a Voronoi diagram; however, it is calculated using distance between generators. The new method is based on the temporal aspect, and the calculated minimum arrival times to all regions of the football field divided by a square meter for each player. We considered the velocity of the players in each frame by referring to previous research. Then, we calculated the dominant values, which showed how long it would take for each of the six players on the two teams to reach the ball position in every frame. In a successful offensive play, the dominant value of the offensive team was larger than that of the defensive team. This finding implies that momentum, that is, the velocities of offensive players, could be evaluated using this new method.
