A minimalist, platform-agnostic package for univariate geophysical data.

Installation | Documentation

From the Julia prompt, type: ] add SeisIO; (Backspace); using SeisIO

Summary | Collaboration

Designed for speed, efficiency, and ease of use. Includes web clients, readers for common seismic data formats, and fast file writers. Utility functions allow time synchronization, data merging, padding time gaps, and other basic data processing.

  • Web clients: SeedLink, FDSN (dataselect, event, station), IRIS (TauP, timeseries)
  • File formats: ASDF (r/w), Bottles, GeoCSV (slist, tspair), QuakeML (r/w), SAC (r/w), SEED (dataless, mini-SEED, resp), SEG Y (rev 0, rev 1, PASSCAL), SLIST, SUDS, StationXML (r/w), Win32, UW

Getting Started | Formats | Web Clients

Start the tutorials in your browser from the Julia prompt with

using SeisIO

To run SeisIO package tests and download sample data, execute

using Pkg, SeisIO; Pkg.test("SeisIO")

Sample data downloaded for the tests can be found thereafter at

sfdir = realpath("../test/SampleFiles/")
