Geopsy team is developing, distributing and maintaining open source software for geophysical research and application. Born during SESAME European Project, it has provided tools for processing ambient vibrations with site characterization in mind. Progressively, more conventional techniques (such as MASW or refraction) are included to offer a high quality, comprehensive and free platform for the interpretation of geophysical experiments.
The distributed package is mainly organized in two parts:
- Signal database and processing with geopsy;
- Inversion with dinver.
This is the official documentation maintained by the developers and the core community of users.
Installation
Geopsy applications and libraries are virtually available for all platforms supported by Qt. However, only the most common ones are supported by Geopsy project.
Quick start tutorials
Applications
Graphical user interface are marked with bold face.
- warangps: monitoring of real-time positions for WARAN, computation of theoretical array responses.
- dinver: inversion with [Neighborhood Algorithm] modified after Wathelet (2008): e.g. surface wave inversion
- figue: edition of figures extracted from processing applications. Figures produced by [figue] are ready for publications (export to ps, pdf, svg, jpeg, png, or printer).
- geopsy: graphical user interface that accepts various wave formats, visualization of waves and basic signal processing.
- gpdc: computation of dispersion curves.
- gpdcmisfit: recompute misfits of models produced by an inversion.
- gpdcreport: analysis of inversion report (from dinver).
- gpec8: determine site class from Vs profiles (Eurocode 8).
- gpell: computation of ellipticity curves.
- gpgroup2phase: scan possible phase dispersion curves from a group dispersion curve.
- gplivemodel: interactive plot of dispersion, ellipticity and SH amplification curves.
- gpmodel2param: transform a model file into a parametrized ground structure
- gpparam2model: produce model files from parameter sets and a given parametrized ground structure.
- gppoisson: simple converter between Poisson's ratio, Vs, and Vp.
- gpprofile: extract Poisson's ratio, Vs, or Vp profiles from a model file.
- gprefra: computation of travel time.
- gpsh: computation of sh transfer curves (available but empty).
- gpsort: re-arrange curve order in a file (handy for gppac output).
- gpspac: computation of auto-correlation ratio curves.
- gpdepth: computes a parameterization from minimum and maximum wavelength
- gpsignal: compute synthetic signals
- gpviewdcreport: plot inversion reports (from dinver).
- max2curve: tool for estimating the average and the uncertainties of various processes: FK, HRFK, SPAC, HVTFA or simply curves.
- spac2disp: tool for estimating the reliability of experimental auto-correlation curves.
