Software

In the seismology program at the University of South Carolina we have an active software development effort. Current projects are listed below.

• Seisplotjs

  Seisplotjs is a javascript library for retrieving, processing and displaying seismic data in the browser. Documentation and examples are available at https://crotwell.github.io/seisplotjs/.

• TauP

  TauP is a seismic travel time calculator. In addition to travel times, it can calculate derivative information such as ray paths through the earth, pierce and turning points. It handles many types of velocity models and can calculate times for virtually any seismic phase with a phase parser.

• Standing Order for Data

  SOD, Standing Order for Data, is a framework to define rules to select seismic events, stations, and data. It then allows you to apply processing to the events, stations, and data and currently contains a large set of rules that allow you to select with great precision in these items. The processes mainly consist of simple data transformation and retrieval, but SOD defines hooks to allow you to cleanly insert your own processing steps, either written in Java or an external program.

• SeedCodec

  SeedCodec is a library of seismic compression and decompression routines in java. Currently support is for Steim1 compression, and decompression of Steim1 and 2, dwssn, cdsn and sro. More information can be found here.

• seisFile

  SeisFile is a library for reading and writing seismic file formats in java. Currently support is for SAC, Miniseed 2 and Miniseed 3. More information can be found here.

• simplemseed

  Simplemseed is a python library for reading and writing miniseed 3.

• simpledali

  Simpledali is a python library for communicating with Ringserver from IRIS via the datalink protocol.
