All aspects of data analysis in computer can be addressed as ‘data handling’, or ‘processing’ Igor Morozov University of Saskatchewan, Canada

 Data formats?  Computer language?  Passive or Active-source, Reflection, Refraction, or shallow data?  Common user interface  Concept general and powerful enough for conceivable tasks  Software maintenance, expansion and collaboration Not Important Very Important

 Wide-angle seismic projects (DSS, ACCRETE)  Crustal reflection (Lithoprobe THO S2b)  Ray tracing and modeling (ported ‘rayinvr’)  Time-lapse 3-C 3-D reflection (Weyburn)  Receiver functions (SRP, CD-ROM); migration, 3-D modeling  USArray processing from IRIS web services  Global travel times (ported tau-p travel-time calculator)  Free oscillations of the Earth and Moon (ported Mineos)  Real-time seismic network  600-Texan hi-res 3-D (Hill AFB)  Shallow refl./refr. and surface-wave studies (a couple landfills)  3-D finite-difference modeling (parallel on cluster)  Well logs, processing and modeling  Potential fields (image processing and analysis)

 Batch, high-throughput seismic processing (as Disco, but multicomponent and much more general )  Any data formats as needed (SEGY, SEG2, SEGP, SU, LAS, SAC, ASCII, GSE, NetDC, XML, RSS)  GUI (Qt; as older versions of ProMAX)  2-D/3-D viewer (Open GL)  Interfaces to GMT and Matlab/Octave  Platform for porting all Seismic Unix codes  Interaction with SQL databases, IRIS web services (via ‘wget’)  Operation as a web server  Basically, a platform for writing, running, and maintaining seismic software  C++, with lots of older C and Fortran  ~300 selectable processing tools, dynamically loaded  Software/documentation maintenance tools  Automatic software updates and collaboration support

 Once a good general framework for processing is implemented, everything can be included in it
