Features | Screenshots | Version

Version 6.0

Geogiga Reflector 6.0 has following improvements:

• Receiver coordinates can be loaded from a text file when seismic data is imported.
• The auto fill feature in importing seismic data is imporved to allow a column to be individually filled with any two nearest rows.
• 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.
• Time-variant band pass filter includes Butterworth and Ormsby filters.
• Frequency scan includes Butterworth and Ormsby filters.
• F-K and Tau-P filters are improved to work with ultrasonic data.
• The Tau-P spectrum can be viewed as wiggle or color density.
• The annotation on the Y axis is improved when the stack is overlaid by velocity section or when the depth stack is loaded.
• 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.

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

Version 5.5

The update in Geogiga Reflector 5.5 includes:

• Add a column for shot depth input when importing seismic data.
• Simplify the procedure of field statics correction with Undo and Redo support.
• Incorporate source depth correction into the field statics correction.
• Add a coordinate tolerance with gather sorting.
• Allow inverse CDP numbering.
• Fix the bug with AGC for extreme small seismic data values.
• Clip the swing of trace wiggle to half of the spacing between traces.

Version 5.4

Following new features are available in Geogiga Reflector 5.4:

• Import seismic data with geometry assignment and file integration.
• Save a single gather in the order of CDP, common offset, common shot, or common receiver. The common offset section can be input to Geogiga SF Imager for further process.
• Define annotation fonts for curve plotting.
• Enhance SEG-Y data loading.
• Specify the measurement units.
• View the Sample Rate in the Trace Display dialog box.
• Add the getting started guide.

For details, please refer to features_seismic09.pdf.

Version 5.3

The new features in Geogiga Reflector 5.3 are listed as follows:

• Provide high resolution Tau-P mapping.
• Test apparent velocity when performing F-K filter or Tau-P filter.
• Display stack of current gather in the analysis of velocity spectra.
• Define resolution when an image is saved.
• Frequency scan.
• Support data file larger than 3GB.

For details, please refer to features_reflector53.pdf.

Version 5.2

Geogiga Reflector 5.2 fixes following bugs:

• Rescale the image in the dialog of F-K filter.
• For ultra-long sampling length, the full frequency range can not be displayed in band-pass filter.
• Abnormal exit when a stack file is saved.

Version 5.1

The update of Geogiga Reflector 5.1 includes:

• Display time in milliseconds instead of seconds.
• Add the phase shift in F-K Filter to reduce the aliasing.
• Speed up the automatic velocity update in Velocity Analysis.
• Be able to adjust the display in the individual sub windows in Velocity Analysis.
• Fix the bug when the velocity analysis window is switched between Semblance Spectra and Velocity Scan.
• Zoom in the seismic display with the left mouse button + [Shift], and Autofit the whole window with the shortcut of [Ctrl] + A.
• Add the shortcuts of [Ctrl] + R and [Ctrl] + U for Redo and Undo.
• Provide "Licence Update Utility".
• Fix the un-installation problem from "Start->Program".
• Add the shortcut of "Contact Us" from "Start -> Program".

Version 5.0

Geogiga Reflector 5.0 adds following new features:

• Improved semblance velocity analysis.
• NMO and inverse NMO correction.
• Multiple regions definition.
• More operations for single record.
• Enhanced controls on trace display.
• Geometry QC with layout chart.
• Extra-large image saving.

Version 4.0

Geogiga Reflector 4.0 fixes some bugs in version 3.3, and adds following new features:

• Regional data editing.
• Time variant band-pass filter.
• Accurate determination of Undo/Redo steps.
• Floating time window within the residual static correction.

Version 3.3

The upgrade of Geogiga Reflector 3.3 includes:
