Example of Spatiotemporal Movement of one person. Spatiotemporal activity pattern of a selected patient during one day. The ST-DBSCAN algorithm estimated six clusters in this case. Numbers denote GPS signals of a specific cluster in temporal order of recording (1 = first cluster, 6 = last cluster recorded throughout the day). Color-shaded areas refer to the hulls around individual clusters. The broken line denotes the hull boundary around all GPS signals recorded during the entire day. Grey dots denote GPS signals allocated to “in transit” destinations. 1=turquoise, 2=brown, 3=violet, 4=red (carmine), 5=green, 6=yellow
