Geogiga EFit 9.3 — Interactive Event Fitting Tool

EFIT allows you to load or interactively define a velocity model and fit the synthetic refraction and reflection curves to the corresponding events on seismic records.


  • Load velocity model from a text file
  • Interactively define velocity model
  • Calculate and display synthetic reflection and refraction curves
  • Load multi-records
  • Check and define geometry
  • Correct trigger delay
  • Automatic gain control (AGC), trace balance, and time variant scaling
  • Butterworth and Ormsby filters with band pass, low pass, high pass, band reject, and notch options
  • Undo and redo multi-step processing on seismic data
