Tracking data are series of\nlocations with at least 2-dimensional spatial coordinates\n(x,y), a time index (t), and individual identification (id) of\nthe object being monitored; movement data are made of\ntrajectories, i.e. the line representation of the path,\ncomposed by steps (the straight-line segments connecting\nsuccessive locations).
