SPEDAS Graphical User Interface


Welcome to SPEDAS

Here you can find information and documentation for the Space Physics Environment Data Analysis Software (SPEDAS) framework. SPEDAS version 1.00, including version 9.0 of the THEMIS Data Analysis Software (TDAS), and updated versions of several other plugins, was released on Aug 29, 2014.

SPEDAS is a grass-roots data analysis software for the Space Physics community. It supports multi-mission data ingestion, analysis and visualization. It standardizes the retrieval of data from distributed repositories, the scientific processing with a powerful set of legacy routines, the quick visualization with full output control and the graph creation for use in papers and presentations.

The SPEDAS framework:

  • Contains a Graphical User Interface for ease of use by novice users.
  • Works with Windows, Linux and Mac OS X.
  • Is based on IDL, benefiting from platform independence and software maintenance services.
  • Can be used with or without an IDL license.

SPEDAS supports plugin modules for multiple projects (THEMIS, GOES, WIND, ERG, etc) and provides interfaces for software modules developed by the individual teams of those missions.

SPEDAS is concerned mostly with establishing developers' guidelines, communicating best practices, and providing peer review of new products to like-minded colleagues, towards an efficient space environment data analysis suite of software code.
