FIRSTOMO


FIRSTOMO is a seismic tomography software for 2D and 3D inversion. It interprets crosshole, VSP and virtually any array configuration data on a standard PC running DOS or a UNIX workstation in 2D or 3D.

FIRSTOMO inverts 2D and 3D traveltime and 2D amplitude data. 2D and 3D kinematic modeling is also possible. The velocity or attenuation model can be entered with the mouse pointing and dragging the model or entering values for cells.
All models can be saved into a database. First arrival times can be input by a simple ASCII file. Raypaths can be visualized and overlayed to the refined model.



 

FIRSTOMO supports metafile output for graphics in various formats such as TIFF, HPGL and GXF or Postscript for Unix systems.
XYZ data for user gridding in various formats can be exported. Complete statistics and ASCII results can be written. Full color control and interactive help options are embedded into FIRSTOMO.



 

FIRSTOMO under DOS runs in protected mode. The maximum number of cells is principally unlimited and depends on your available memory. PC must have 486 processor or higher, DOS 3.11 or higher and 2MByte of free disk space.
