HinetPy 0.3.1

A NIED Hi-net web service client and win32 tools for seismologists.

HinetPy is a Python package aiming to automate and simplify tedious data request, downloading and format conversion tasks related to NIED Hi-net.

Dependencies

1. Python 3.4+

2. requests

3. win32tools provided by NIED Hi-net

Features

1. Automatically request continuous waveform data from Hi-net

2. Convert win32 data into SAC format

3. Extract instrumental response as SAC PZ file

A simple example

It’s simple to request a continuous waveform data from Hi-net, convert the data into SAC format and extract instrumental response as SAC PZ file.

>>> from HinetPy import Client, win32
>>> from datetim import datetime
>>>
>>> # You need a Hi-net account to access their data
>>> client = Client("username", "password")
>>>
>>> # Let's try to request 20 minutes data since 2010-01-01T00:00(GMT+9) from Hi-net
>>> starttime = datetime(2010, 1, 1, 0, 0)
>>> data, ctable = client.get_waveform('0101', starttime, 20)
>>> # The request process takes several minutes due to the unfriendly design of Hi-net
>>> ls  # the downloaded data and corresponding channel table
0101_201001010000_20.cnt 0101_20100101.ch
>>>
>>> # Let's convert win32 data into SAC format
>>> win32.extract_sac(data, ctable)
>>> ls *.SAC
N.NGUH.E.SAC  N.NGUH.U.SAC  N.NNMH.N.SAC
N.NGUH.N.SAC  N.NNMH.E.SAC  N.NNMH.U.SAC
>>>
>>> # Let's extract instrument response as PZ file from channel table
>>> win32.extract_pz(ctable)
>>> ls
N.NGUH.E.SAC_PZ  N.NGUH.U.SAC_PZ  N.NNMH.N.SAC_PZ
N.NGUH.N.SAC_PZ  N.NNMH.E.SAC_PZ  N.NNMH.U.SAC_PZ
