Filter time-series based on sun movement
pip install dayfilter
DayFilter depends on suntime. Due to known issue of suntime, please use my fork of suntime on test-pypi. To install, use:
pip uninstall -y suntime
pip install -i https://test.pypi.org/simple/ suntime-yasirroni
I can't bundle my fork of suntime into DayFilter due to LICENSE incompatibility issue.
Simple use case of getting list of bool
from datetime import datetime
from dayfilter import is_daytime
date_string = '2010-01-01-16:58:30.00000'
date_datetime = datetime.strptime(date_string, '%Y-%m-%d-%H:%M:%S.%f')
# WASHINGTON DC DULLES INT'L AR [STERLING - ISIS], VA. data
latitude = 38.98
longitude = -77.47
time_zone = -5
is_daytime(date_datetime, latitude, longitude, time_zone)Using DayFilter class for multiple call
from dayfilter import DayFilter
import pandas as pd
from datetime import datetime
# WASHINGTON DC DULLES INT'L AR [STERLING - ISIS], VA. data
latitude = 38.98
longitude = -77.47
time_zone = -5
f = DayFilter(latitude, longitude, time_zone)
date_strings = [
'2010-01-01-05:58:42.00000',
'2010-01-01-06:59:22.00000',
'2010-01-01-13:22:23.00000',
'2010-01-01-14:54:55.00000',
'2010-01-01-15:31:45.00000',
'2010-01-02-17:12:22.00000',
'2010-01-02-15:12:32.00000',
'2010-01-02-16:59:32.00000',
'2010-01-02-18:00:11.00000',
]
date_format = '%Y-%m-%d-%H:%M:%S.%f'
date_datetimes = [datetime.strptime(date_string, date_format) for date_string in date_strings]
df = pd.DataFrame(index=date_datetimes, data=[1,2,3,4,5,6,7,8,9])
df_ = f.filter(df)
print(df_)Adcanced use of DayFilter class with custom filter
from dayfilter import DayFilter
from dayfilter.post_process import shift_sr_down, shift_ss_up
from dayfilter.logic import logic_daytime
f2 = DayFilter(latitude, longitude, time_zone, post_processes=[shift_sr_down, shift_ss_up], logic=logic_daytime)
df__ = f2.filter(df)
print(df__)
print(f.get_sr_ss(df_.index[0]))
print(f.get_sr_ss(df_.index[0], post_processes=True))- Consider refactor to astral due to suntime LICENSE. a. Astral is slower and have same bug with the original suntime b. Soulution of the suntime bug exist on yasirroni/suntime
