Main features of SIA system

• Native support of complex, structured, 2-D and 3-D seismic data sets
• High data pass-through characteristic of commercial seismic packages
• More flexibility in data manipulation than most seismic processing packages
• Powerful job description language, modern, user-friendly Graphical User Interface
• A variety of data types:

  Multicomponent, variable-length and variable-sample interval seismic trace records,

  Database tables,

  Several kinds of velocity models,

  Potential-field data grids,

  Images,

  User-specified arbitrary data types.

• Integration of many types of existing seismic, mapping, modeling, inversion, and other software:

  Piping of the data flow into/from Seismic Un*x processing flows, potentially includes most of SU programs

  Interface to Generic mapping Tools (GMT);

  Earthquake data readers  SAC, GSE3.0, CSS3.0 (RDSEED also available but needs updating to the newest IRIS version...),

  Reflectivity (synthetic wavefield computations in 1D models by Fuchs and Muller),

  Rayinvr (2-D ray tracing by Zelt and Smith) with greatly enhanced model editing functionality;

  Inversion algorithms: LS, ART, LSQR, Artificial Neural Networks and Genetic Algorithms

• Some original seismological algorithms:

  Multicomponent seismic attribute extraction, high resolution velocity analysis, separation of P and SV waves,

  Statistical coherence measures, ray tracing, travel-time inversion, attenuation measurements;

  Velocity and attenuation tomography,

  Sensitivity testing of ray-tracing velocity models and travel-time inversion using genetic algorithms;

  Wide-angle migration and depth focusing package in 2D and 3D, both for wide-angle and receiver function work;

  And other…

• Grid and cluster functionality (currently via PVM)
• Customizable interactive 3D/2D OpenGL graphics (currently in the works...)
• Web service operation
• System maintenance utilities and automated software and documentation updates
• Diagnostic tools
