obspy.signal.array_analysis.get_geometry

get_geometry(stream, coordsys='lonlat', return_center=False, verbose=False)[source]

Method to calculate the array geometry and the center coordinates in km

Parameters

  • stream – Stream object, the trace.stats dict like class must contain an AttribDict with ‘latitude’, ‘longitude’ (in degrees) and ‘elevation’ (in km), or ‘x’, ‘y’, ‘elevation’ (in km) items/attributes. See param coordsys

  • coordsys – valid values: ‘lonlat’ and ‘xy’, choose which stream attributes to use for coordinates

  • return_center – Returns the center coordinates as extra tuple

Returns

Returns the geometry of the stations as 2d numpy.ndarray The first dimension are the station indexes with the same order as the traces in the stream object. The second index are the values of [lat, lon, elev] in km last index contains center [lat, lon, elev] in degrees and km if return_center is true
