Animals: Dataset composed by raw trajectories of three different animal species: elk, deer and cattle. The animal trajectories were extracted by telemetry, between 1993 to 1996 in the Experimental Forest of Starkey. It consists on a sparse dataset, with few, but long, trajectories, and low sampling rate with several minutes of difference between the points. The entire dataset was used, as it has only 253 trajectories, with trajectory size varying from 43 to 4007 points.
