The last decade experienced the emergence of quantitative movement analysis in team sports such as soccer, volleyball, and football. Coaches are continually looking for effective ways to analyze and evaluate their team's tactics objectively and scientifically. Although the last decade experienced the prevalence of tracking technologies such as Global Positioning System (GPS) and Wireless Fidelity (WiFi), little attention is paid to applications of tactical analysis in players' movement especially in soccer. This project proposes an interactive geovisual toolkit for analysis of soccer player movement The toolkit provides various metrics, from simple geometric analysis such as the convex hull of a team or subset of players, to more advanced analyses such as potential movement regions within a few seconds. It also provides detailed statistical information derived from the proposed metrics to summarize the movement characteristics of individual players and the team. In addition to statistical data about player movements or configurations, the toolkit visualizes these metrics in a GIS environment. The combination of proposed metrics with visualization detects critical moments during play that can be further analyzed with game film. Furthermore, this study develops metrics to analyze interactions between players and the soccer ball. The metrics of interactions between multiple objects in a planar space uncover movement patterns emerging from both interactions between players from players in two teams and a ball. The metrics and visualization tool enable coaches to quickly understand where critical game moments occur by breaking down complex interactions between players.
