The program Reflex 2D-Quick allows an easy import, display, processing and interpretation of 2-dimensional GroundPenetratingRadar zero offset and seismic single shot data (click on the datatype for a video guide) . The program is free for Reflexw 2D-dataanalysis users but it can also be ordered as a lowcost standalone processing tool (see order button at the end of this page). The program offers the following possibilities:
The program is useful for the following applications:
processing and display
The following processing options are available:
The picture on the right shows a GPR example
The are many different display possibilities like point or wiggle mode, scaling and zooming functions available.
The data may be exported to the clipboard or saved as ASCII- or bitmap-data.
Printing is possible with freely choosable scale either in cm or scale like 1:1000 with a print preview menu which allows to preview the size and shape of the print output and to define an individiual print header.
An interactive hyperbola-adaption for a simple determination of the average velocity from a zero-offset or CMP profile (see figure on the left) is integrated (see picute on the left). It is possible to adapt diffractions, reflections and straight lines. You may change the velocity, the radius of the target, the angle between the line and the target and the width of the calculated diffraction or reflection hyperbola. There is also the possibility of fitting linear features either by changing interactively a line or by setting two points. The option core allows to vary interactively the velocities of the single layers of the individual cores stored within an ASCII-file.
In addition an interactive use of the intercept time method for seismic refraction data is included (see picture on the right). The option enables to get a first 1D-model very quickly.
Picking the onsets/first arrivals
The picking option allows to pick the traveltime and the amplitude of different onsets like reflectors or hyperbola or the first arrivals. You have the choice between manual picking, continuous picking and a semi-automatic picking using a phase follower (manual editing is always possible).
The so called layer-show (see picture on the right) offers the possibility to combine individual pick files, to plot them together with the wiggle-files and to output them in report form on printer or file containing the depths, velocities and amplitudes of the individual layers. The time-depth conversion of the picks is either based on a constant velocity for each layer or on a 2-dimensional velocity distribution allowing to take into account vertical and lateral velocity changes.
