Geogiga Surface 7.0 - Surface Wave Data Processing Software
Features | Screenshots | Version | Comparison
Geogiga Surface calculates the dispersion spectrum in F-K, F-V, or F-P domain, where the dispersion curve is interactively picked. The robust forwarding scheme and the nonlinear optimal genetic algorithm (GA) assure the quick converge of inversion.
Geogiga Surface is able to process active surface wave at a single location or multiple locations along a line. The section can be displayed as curves, contours, color, or editable stratigraphic symbols.
Main Features:
- Process active surface wave data
- Load all shot records along a line at once, browse and select any record for QC
