Passive Surface Wave Data Analysis
- Import passive surface wave data recorded by nodal or conventional seismometers
- Support any type of 1D or 2D arrays and 3D coordinates
- Display frequency spectra of any time segments
- Azimuth analysis for 2D arrays
- Select traces for dispersion analysis
- Extract dispersion curves with SPAC functions
- Generate dispersion images with ESPAC, SPAC, REMI or FK
- Combine dispersion images of multiple passive surface wave records
- Combine dispersion images of active and passive surface wave data
