Welcome to GeopsyWiki

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.

• Linux

• Mac OS X

• Microsoft Windows

User documentation

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.

Quick start tutorials

• Loading and viewing signals
• H/V spectral ratio
• Ambient vibration array
• Active source experiment (MASW)
• Dispersion curve inversion

Application reference manuals

The distributed package contains more than 50 items (applications and plug-ins). They can be organized in various categories and lists:

• Synopsis: a graphical map of all applications and items[1]
• Signal processing: storage and processing of experimental recordings
• Inversion: inversion and surface wave computations
• Graphical engine: how to handle figures and plots produced by Geopsy.org applications.
• Wireless ARray ANalysis acquisition system: a list of softwares developed for pseudo-real time processing of ambient vibrations

Man pages

All Geopsy.org softwares accept command line options, even graphical interfaces like geopsy or dinver. Man pages are equivalent to -h or -help options. Note that under Windows using MSYS console is strongly recommended to fully exploit all possibilities of shell scripting (do not use the default MS-DOS console).

General scientific background

• Nature of ambient vibrations
• H/V Single station processing
• Array signal processing
• Dispersion curve interpretation
• Inversion problems

Developer documentation

This section is of interest only for people who wants to be involved in code development, bug fixes or administration.
