Geogiga Refractor 7.0 - Seismic Refraction Data Processing Software

Features | Screenshots | Version

Version 7.0

Geogiga Refractor 7.0 has following new features and improvements:

• Geometry can be redefined after seismic data is loaded.
• Elevation data can be copied from other text editors with the Ctrl-C and Ctrl-V keys.
• Trigger delay correction can be applied on seismic data and TX curves based on specified time or surface velocity.
• Auto-pick first breaks guided with apparent velocity and/or wavelet phases.
• Show all or single record(s) in the dockable Trace View.
• The time range of curve display can be synchronized with that of trace display.
• Trace wiggles can be plotted with positive or/and negative fill in different colors.
• Trace graphs are plotted.
• Colormaps can be customized.

For details, please see Geogiga Seismic Pro 7.0 release notes.

Version 6.0

Geogiga Refractor 6.0 has following improvements:

• Receiver coordinates can be loaded from a text file.
• The auto fill feature in importing seismic data is imporved to allow a column to be individually filled with any two nearest rows.
• Seismic data is sorted according to receiver locations instead of receiver numbers.
• The reverse geometry definition is supported.
• The frequency filter includes Butterworth and Ormsby filters with the option of band pass, low pass, high pass, band reject, and notch.
• A window is used in the frequency filter to reduce the energy leakage caused by FFT.
• The spectrum curve in the frequency filter dialog box can be displayed as amplitude or power in dB or relative values with customized view settings.
• The extreme long sample length is well handled in the frequency filter.
• In the trace magnifier, the first arrival of a trace is automatically tracked according to the first arrivals of its nearest traces.
• The layer assignment and phantom are checked before the GRM, Delay Time and ABC methods are used.
• The calculation of reciprocal time is improved according to the base shots rather than the end shots.
• The view points of receivers on TX curves can be turned off and customized.
• The annotations on axes are better aligned to avoid the labels overlapped.
• When a variety of data is saved, the output directory is checked and an appropriate extension is automatically appended to the output filename.
• Any extra margin is removed in saving an image.
• The user guide is updated.
• The version number consists with Geogiga Seismic Pro.

Version 4.2

The update in Geogiga Refractor 4.2 includes:

• Clip the swing of trace wiggle to half of the spacing between traces.
• Label receiver locations instead of trace numbers in the picking view.
• Enable to modify geometry after loading seismic data.
• Save seismic data in a different file.
• Match seismic data and TT curves according to geometry rather than shot number.
• Reset the browse path when opening curves.
• Better default axis labels for the color section display.
• Fix the bug when plotting the depth section with higher elevation.
• Fix the bug with AGC for extreme small seismic data values.
