IGeoS - Integrated GeoScience data analysis

IGeoS is a highly integrated software package used for many seismic processing tasks in a wide range of geophysical, and ultimately geoscience data analysis. It is being continuously developed since mid-1995 by Igor Morozov, now at UofS seismology, as a framework for integration of geophysical software. 

Previously, the system was called SIA. We have changed the name to IGeoS to reflect the broader (no longer strictly seismic) orientation of the package. 

In our research, we use many types of geophysical data, all of which are being managed and processed in IGeoS:

• Reflection and refraction seismic records in complex 2-D and 3-D survey geometries,
• Multicomponent seismic datasets;
• Local to ultra-long range earthquake and nuclear explosion seismic records, 
• Real-time (Internet seismic network) data management; 
• Ground Penetrating Radar records;
• 1-, 2-, and 3-D seismic waveform simulations.
• Travel-time curves, surfaces, and tables, 
• Various types of  velocity and density models,
• 2D and 3D potential-field datasets.

IGeoS can also be viewed as a framework for integration, development, and maintenance of geophysical software. 

General architecture of IGeoS system

Examples:

Here are some examples of applications using interactive 3D visualization:

• Displays of seismic records
• 3D travel-time picking and Refraction Statics inversion tools 
• Seismic Acoustic and Elastic Impedance inversion
• Wide-angle seismic ray tracing
• Interactive Receiver Function modeling and analysis 
• Gravity and magnetic fields
• Earthquakes
• Real-time seismic records

In current development:

• Well-log handling, transformation, and analysis package;
• Amplitude Variation with Offset (AVO) package;
• Package for direct handling of 3D and 4D reflection seismic data;
• Complete refraction statics package (automatic and manual picking, quality control, and inversion);
• Attribute extraction and Empirical Mode Decomposition on 2D potential-field grids;
• 3D parallel visco-elastic finite difference simulator with arbitrary surface topography;
• 3D generalized cylindrical screen propagator;
• Uniform database interface (internal and for SQL-based external databases);
• Real-time data acquisition and processing;
• Streamlined configurations and demo sets for exploration industry applications.

I invite contributions from others on the above and other topics.

• Code maintenance and package administration utilities;
• Seismic Unix (SU) interface allowing utilization of the entire SU package;
• Interfaces to other free popular packages, such as GMT;
• Unique web-based capabilities:
  • Collaboration tools for remote data processing and modeling 
  • Development and code maintenance
• More detail on the principal distinctive features of the system.

Web services:

• Data processing web service

Reference information:

• Library of processing examples. Note that you can add to these pages, and also that some of these examples are executable and might be useful.
• Summary of DISCO-style job scripting language.  Note that the GUI can also use an XML format for saving jobs.
• Index of IGeoS(SIA) modules ... this is automatically maintained, so it should be almost up to date!
• C++ code documentation by Doxygen:
  • Main libraries
  • GUI, 
  • OpenGL display server
  • Module code documentation is available through the Module index
• System description..
• Programmer's reference ... incomplete and not up to date...
• C++ code templates
• Porting tool codes written for DISCO 
• Using Seismic UNIX codes and processing flows in IGeoS
• Miscellaneous info

Distribution, installation, and administration:

• The system had been extensively used on Solaris, SGI Irix (batch modes only), and more recently on Fedora 6-11, Mandrake, Mandriva, Red Hat Enterprise, and SUSE Linux, on several Intel and AMD laptops, desktop workstations, and clusters (both 32- and 64-bit), Mac OS X or Ubuntu 9.
• Solutions for maintaining multiple binaries for different architectures from a common source code are provided.
• Note that the code distribution below is provided by two live IGeoS installations on 32-bit and 64-bit Linux machines which are also being used in processing data.
• Installation instructions and map
• Code maintenance web service
• System administration
