Features | Screenshots | Version

Version 6.0

Geogiga Front End 6.0 has following new features and improvements:

• 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.
• Amplitude decay analysis is added.
• Vertical stacking is available.
• Any extra margin is removed in saving an image.
• The user guide is updated.
• The version number consists with Geogiga Seismic Pro.

For details, please see Geogiga Seismic Pro 6.0 release notes.

Version 2.6

The update in Geogiga Front End 2.6 includes:

• Correct the trigger delay graphically or manually for a single record.
• Trigger delay correction for multiple records.
• Add the Batch Commands tab panel, including Batch Resample, Batch Define Geometry, Integrate Files, and Batch Trigger Delay Correction.
• Fix the bug with AGC for extreme small seismic data values.

For details, please refer to features_seismic09_06.pdf.

Version 2.5

Following new features are available in Geogiga Front End 2.5:

• Shift a seismic trace with Undo/Redo supported.
• Save files in a specified directory.
• Automatically change the output suffix according to different formats.
• Enhance SEG-Y data loading.
• View the Sample Rate in the Trace Display dialog box.

For details, please refer to features_seismic09.pdf.

Version 2.4

Geogiga Front End 2.4 adds following new features in batch geometry assignment:

• Assign geometry for passive surface wave.
• Define the geometry of multi-records at same shot location.
• Plot layout chart as slope or flat.

Version 2.3

The update in Geogiga Front End 2.3 includes:

• Display time in milliseconds instead of seconds.
• Support non-standard SEG-2.
• Fix the un-installation problem from "Start->Program".
• Add tutorial.

Geogiga Front End 2.3 fixes several bugs when multiple seismic data files are integrated:

• Set the output path and filename by default.
• Sort the files after they are moved up/down in the list.
• Allow the input file with SEG-Y format.

In addition, version 2.3 also fixes the display problem of band-pass filter caused by the super-long sample length and removes the limit on the number of receivers in the layout chart.

Version 2.2

Geogiga Front End 2.2 adds the following new features:

• Swap traces
• Automatically adjusts the display scale when the number of seismic traces is larger than 48.
• Support little endian SEG-Y, auto-check and save SEG-Y data format.
• Check and modify the file property of read/write when the file is saved.

Version 2.1

Geogiga Front End 2.1 fixes several bugs in version 2.0, and adds following features:

• Gain Control including automatic gain control (AGC), trace balance, and time scales.
• Resample seismic data in a batch.
• Sort files with irregular names for batch operations.

Version 2.0

New features in Geogiga Front End 2.0 are listed as follows:

• Scale, mute, average, or reverse seismic traces inside/outside any shape of region.
• Preview layout chart, plot the locations of shots and receivers after batch geometry assignment.
