This module is dedicated to MASW surveys using microphones (SeisMike) that generates a 2D shear-wave velocity (Vs) cross section automatically in real time as data files (SEG-2) are saved by the seismograph. All data-analysis steps of dispersion and inversion, and subsequent presentation of analysis results are optimized for the pavement investigation (concrete or asphalt). This module also provides full manual analysis options so that the user can inspect and adjust analysis parameters as necessary.

SeisMike record (SEG-2) saved by seismograph is displayed after the direct-air-wave (DAW) arrivals are automatically muted (left), and corresponding dispersion image (center) and energy-depth (right) charts are illustrated below.
After a few SEG-2 records are saved, the 2D velocity (Vs) cross section is constructed as illustrated below. It will be continuously expanded in surface distance as more records are saved.
