ISDAT - Interactive Science Data Analysis Tool

Summary of features

Recent progress in computer, mass storage, and network technology has facilitated a dramatic improvement and flexibility in the software tools used for scientific data analysis. ISDAT is a software tool, utilising such modern techniques, under development at the Swedish Institute of Space Physics, Uppsala Division, in collaboration with several other laboratories within the field of experimental space physics.

The ISDAT development started in 1989 by formulating a set of general requirements from a science user's viewpoint. These requirements led to a set of assumptions about the near future computer and software development, a set of standards and an ISDAT development model. At the current stage, the ISDAT software tool is characterized by:

  • An interactive data analysis environment
  • A client / server
  • Great flexibility in the distribution of processing power and data bases
  • Project and instrument specific input formats
  • A very general internal data structure
  • Possibilities to combine data from several projects and instruments
  • A possibility for the user to add personal analysis and display software modules in C or IDL languages.
  • Interfaces to commercial software packages like IDL and MATLAB.
  • Output in CDF, Postscript, or ASCII formats
  • Possibilities to run it on a number of UNIX platforms as well as Open/VMS systems
The ISDAT is currently in use at a number of Research laboratories for analysis of data from the projects Viking, Freja and EISCAT. It will be used for the detailed analysis of the wave consortium (WEC) of the Cluster project. The ISDAT will also constitute one component of the ESA provided Cluster Science data System. As such it will be used to retrieve, manipulate, and display data residing in the Cluster associated National Data centres.

The ISDAT distribution and use is subject to certain rules and limitations. As soon as you have read and agreed on these rules, you are welcome to fetch the documentation of the ISDAT, as well as the isdat code via CVS .

There are also project and instrument specific pages with access restricted to the instrument teams.
