Record shape

{
    "station": "ANMO",
    "channel": "BHZ",
    "starttime": "2024-01-01T00:00:00.000000Z",
    "sampling_rate": 40.0,
    "data": [...],
    "network": "IU",
    "location": "00",
}

network and location may be None. All traces are loaded into memory via ObsPy.

Usage

from iterable import open_iterable

with open_iterable("station.mseed", format="mseed") as source:
    for trace in source:
        print(trace["station"], trace["channel"], trace["sampling_rate"], len(trace["data"]))

Install with pip install iterabledata[geophysical].
