germany_bbox = CountryFilter.countries["Germany"]
cf = CountryFilter(german_bbox)

• _to : dt.datetime=dt.now()
• min_duration_sec : int=0
• max_duration_sec : int=0

Methods

Filtering

Use the filter() method to filter a list of WorkoutRoute. Only routes that were recorded after _from, before _to, with a minimum duration of min_duration_sec seconds and a maximum duration of max_duration_sec seconds will be selected.

Parameters:

• routes : List[WorkoutRoute] -> WorkoutRoute

Returns:

• List[WorkoutRoute] → WorkoutRoute

Usage: routes is a list of WorkoutRoute previously loaded using DataLoader or CacheHandler. The following filter will only select routes that were recorded after the 23. February 2020 and the routes have to be between 30 minutes and 5 hours long.

from watchlib.filtering import TimeFilter

_from = dt.fromtimestamp(1582450784) # 1582450784 = 23.02.2020
_to = dt.now()
min_duration = 60*30
max_duration = 60*60*5

tf = TimeFilter(_from, _to, min_duration, max_duration)
filtered_routes = tf.filter(routes)

# len(filtered_routes) <= len(routes)
