In practice, Geogiga Seismic Pro is a workhorse. A typical application involves a site investigation for a bridge foundation: A geophysicist deploys a 24-channel seismograph with 4.5 Hz geophones. They acquire data using a 10-kg sledgehammer. Within an hour, Geogiga Seismic Pro produces a Vs profile showing 15 meters of soft clay over dense sand. The engineer then uses this Vs30 value (average shear-wave velocity to 30 m) to calculate seismic site class per building codes (e.g., IBC, Eurocode 8). Similarly, the software is used for detecting karst features, assessing liquefaction potential, and mapping the depth to bedrock for tunnel boring.
The software provides clear visual feedback, including misfit plots between observed and calculated dispersion curves, and comparison of raw data with synthetic seismograms. This transparency allows users to assess the reliability of the final Vs model. geogiga seismic pro
Unlike some academic-focused codes that require scripting, Geogiga Seismic Pro relies on a Windows-based GUI. This lowers the learning curve for field geophysicists and engineering geologists who prioritize efficiency over research flexibility. In practice, Geogiga Seismic Pro is a workhorse
While Geogiga Seismic Pro is excellent for standard shallow applications (typically < 30–50 meters depth with active sources), it has limitations. It is not designed for deep crustal studies (kilometer-scale). Furthermore, it is less customizable than open-source alternatives (e.g., Geopsy) or more academic-focused codes (e.g., Dinver). The inversion engine, while robust for simple to moderately complex geology (e.g., velocity increasing with depth, presence of a low-velocity layer), may struggle with highly complex 2D/3D structures. Additionally, the software is commercial; for small consulting firms or academic projects with limited budgets, the licensing cost can be a barrier. Within an hour, Geogiga Seismic Pro produces a
