obspy.core.inventory.station.Station.select

Station.select(location=None, channel=None, time=None, starttime=None, endtime=None, sampling_rate=None, minlatitude=None, maxlatitude=None, minlongitude=None, maxlongitude=None, latitude=None, longitude=None, minradius=None, maxradius=None)[source]

Returns the Station object with only the Channels that match the given criteria (e.g. all channels with channel="EHZ").

Warning

The returned object is based on a shallow copy of the original object. That means that modifying any mutable child elements will also modify the original object (see https://docs.python.org/2/library/copy.html). Use copy() afterwards to make a new copy of the data in memory.

Example

>>> from obspy import read_inventory, UTCDateTime
>>> sta = read_inventory()[0][0]
>>> t = UTCDateTime(2008, 7, 1, 12)
>>> sta = sta.select(channel="[LB]HZ", time=t)
>>> print(sta)  
Station FUR (Fuerstenfeldbruck, Bavaria, GR-Net)
    Station Code: FUR

    Access: None
    Latitude: 48.1629, Longitude: 11.2752, Elevation: 565.0 m
    Available Channels:
     ..BHZ        20.0 Hz  2006-12-16 to None

The location and channel selection criteria may also contain UNIX style wildcards (e.g. *, ?, …; see fnmatch()).

Parameters:

  • location (str) – Potentially wildcarded location code. If not given, all location codes will be accepted.

  • channel (str) – Potentially wildcarded channel code. If not given, all channel codes will be accepted.

  • time (UTCDateTime) – Only include channels active at given point in time.

  • starttime (UTCDateTime) – Only include channels active at or after given point in time (i.e. channels ending before given time will not be shown).

  • endtime (UTCDateTime) – Only include channels active before or at given point in time (i.e. channels starting after given time will not be shown).

  • sampling_rate (float) – Only include channels whose sampling rate matches the given sampling rate, in Hz (within absolute tolerance of 1E-8 Hz and relative tolerance of 1E-5)

  • minlatitude (float) – Only include channels with a latitude larger than the specified minimum.

  • maxlatitude (float) – Only include channels with a latitude smaller than the specified maximum.

  • minlongitude (float) – Only include channels with a longitude larger than the specified minimum.

  • maxlongitude (float) – Only include channels with a longitude smaller than the specified maximum.

  • latitude (float) – Specify the latitude to be used for a radius selection.

  • longitude (float) – Specify the longitude to be used for a radius selection.

  • minradius (float) – Only include channels within the specified minimum number of degrees from the geographic point defined by the latitude and longitude parameters.

  • maxradius (float) – Only include channels within the specified maximum number of degrees from the geographic point defined by the latitude and longitude parameters.
