The program Reflex 3D-Scan allows to import and to analyse automatically rectangular 3-dimensional GPR- or seismic data which have been acquired along 2D-parallel lines in one or two perpendicular directions. The program is free for Reflexw 3D-datainterpretation users but it can also be ordered as a lowcost standalone processing tool (see order button at the end of this page).
Precondition is that the data have been acquired along equidistant parallel 2D-lines on a regular rectangular grid. This means that the traceincrement in one direction (x or y), the number of traces into this direction, the start- and endpositions of the 2D-lines and the scan increment between the 2D-lines must be equal. In addition if the data have been acquired in two perpendicular directions (see right picture) the increment between the parallel lines (scan increment) must equal the traceincrement.
If these preconditions are satisfied the 3D-scan program allows a very fast interpretation of your 3D-data.
Different dataformats are supported (see picture on the left). The original data may be stored on individual 2D-files or on one 3D-file with the 2D-lines sequentially stored. With 2D-files acquired an automatic interpolation filter allows a resampling of the data in the direction of each line if the number of traces slightly differ in each 2D-line.
Optionally some filter steps are automatically performed. They are: dewow, static correction, background removal, migration (2D and 3D) and gain in timedirection.
The processing of the x- and y-scans may be done independently and the c-scans also may be built independently choosing the envelope of the original data.
Within the 3D-GPR ScanView menu which opens after all sorting and processing steps have been finished all display options of the 3D-datinterpretation are available (option windows, option scroll and option 3D-cube - see also Reflexw 3D-datainterpretation).
A MPEG moviefile for the later use with a MPEG-player may be easily constructed for the scroll and the 3DCube mode.
Optionally the actual timeslice depending on the mouse position is shown in a second window (see picture on the left). The actual cursor position is marked by a cross within the timeslice.
