dpd-lib 0.1.0

A package for interacting with the USGS influx db

Derived Project Database Library

Overview

This libary contains several functions that enable the processing, storage, and retrieve of seismic and infrasound signal data. The underlying storage mechanism that sits under each respective component is an InfluxDB database that we call the Derived Product Database (DPD).

The DPD is a time-series storage system that contains processed seismic and infrasound signal data. In theory, the DPD can be extended to store any time series data and the dpd_lib can be used to upload and retrieve that data assuming the underlying system has been set up correctly.

The DPD Library

The DPD Library is a python library comprised of a number of functions that enable users to upload and retrieve signal data stored in an underlying DPD. The functions typically follow the following format:

• read_[signal_type]()
• record_[signal_type]()
• list_[signal_type]()

So, for example, to retrieve infrasound data, one would import and use read_infrasound() with the proper arguments. Just like with the DPD Agent, the DPD Library depends on four InfluxDB environment variables to run.

The library can be found at pypi.org and installed using pip.
