The file "movement" contains 12 days' trajectories of one
person on his way between home and office in a car, where the data are collected
from a GPS sensor carried by the person. It contains 4 outlier regions as
follows, each of which is a seldom event in some day's trajectory of the 12
outlier 1: 5-10, localization error.
outlier 2: 6180-6330, the car detour due to some road maintenance.
outlier 3: 11320-11500, the person goes out of the car to a nearby school, then goes back to the car.
outlier 4: 16300-16500, the person goes out of car to a nearby park and goes back to the car.
outlier 5: 30052-30010, localization error.
outlier 6: 31320-31563, the person goes out of the car to a book store, and then goes back to the car.
Note: 1. the two localization error looks similar, maybe due to the same problem of sensors.
2. the book store in outlier 6 is near the school in outlier 3.
