Inversion |
|||

dinver |
Graphical environment to solve inversion problem using Neighborhood Algorithm or Monte-Carlo sampling. Various plugins are proposed here for solving common problems. You can define your own based on the template provided here below. | ||

dinverdc |
Inversion of dispersion curves (Rayleigh, Love, Phase and Group velocities, higher modes), autocorrelation curves, ellipticity curves, ellipticity peak and refraction travel times. Joint inversion are also possible. | ||

dinverext |
Plugin to run the forward computation in an external command. | ||

New |
|||

GeopsyLand |
New item, no description available yet. | ||

Plotting |
|||

figue |
Figure edition. A graphical tool to merge various plots picked in all other geopsy softwares. Creating XY plot from command line is a breeze. It can also export to ps, pdf and bitmap image formats. | ||

geopsyfigs |
Plugin needed to export graphic signal from Geopsy to Figue. | ||

gpcoord |
Coordinate X,Y operations: distance, azimuth, conversion from/to lat/long, array limits,... | ||

gpcurve |
Curve processing: resample, cut, interpolate, derivate, integrate,... Exactly the same actions as inside Dinver (module dinvedc) but through a command line. It can also sample an analytical expression to generate functions. | ||

gpdistance |
Calculates distances and azimuth between named points (aka stations). Uses a lookup table for station coordinates. Such lookup is difficult to implement with awk, the reason for writing it in C++. | ||

gphistogram |
Constucts interactive 2D histograms from any data set (couples X, Y). | ||

gpmaplayer |
Build a geo-referenced background map from Google static API and save it as a .layer file. Useful for WARAN station positionning in urban environment. | ||

gpsort |
Sort curves stored in a text file (one after the other, various columns for X, Y,...). Usefull to re-order curves produced by gpspac and pipe them to figue in the correct order (play with option '-cpp'). | ||

gptime |
Converts time formats. | ||

gpviewmax |
Data analyser for Love/Rayleigh FK max files. | ||

Signal Processing |
|||

campbelltob3 |
A module to load Campbell TOB3 files, written for CR6 | ||

geopsy |
Graphical environment to view, organize and process signals. Most of the geophysical file formats are automatically recognized. Geopsy features can be extended through plugin tools. A selection is available here below. | ||

geopsyarray |
Plugin tool to extract dispersion/autocorrelation curves from arrays of stations. It includes processing for both passive and active recordings. Main contributions from M. Ohrnberger and A. Khoeler (University of Potsdam). | ||

geopsydamping |
Plugin tool to compute damping: based on random decrement for a single station measurement. Based on original Phd work of F. Dunant (LGIT, 2005, These_fdunand.pdf). | ||

geopsyhv |
Plugin tool to compute H/V spectral ratios from single station ambient vibrations. A sub-product from SESAME European project (2001-2004) with main contributions from J.-L. Chatelain (aka 'Gaillot'), B. Guillier and P.-Y. Bard (LGIT). | ||

geopsynr |
Plugin tool to increase (or to try to) the signal to noise ratio in active seismic. Basic and enhanced stacking technique. T0 adjustment (even to a fraction of sampling period). | ||

geopsyptmotion |
Plugin tool to plot particle motion from 3-component recordings (projection on all planes). | ||

geopsyrefra |
Plugin tool to pipe picked arrival times from Geopsy to Dinver. | ||

geopsytfa |
Plugin tool to compute a time-frequency analysis based on Morlet wavelet. Main contributions from M. Kristekova (University of Bratislava). | ||

gpfksimulator |
Educational tool for FK array response | ||

gpsignal |
Computation of custom cosine signals. Stacks of multiple frequencies and phases. Support for phase shifts between various station locations. | ||

hvtfa |
Plugin tool to extract Rayleigh ellipticity from single station measurements (still experimental). | ||

spac2disp |
Post processing tools for SPAC method. Check consistency between autocorr curves computed for various rings. Based on original work from Wathelet et al. (2005). Support for 1C and 3C analysis. | ||

vslarray |
Virtual Seedlink Array: emulate a real-time WARAN acquisition from a Geopsy database. Requires the installation of Seiscomp>=2.6 with mscan plugin | ||

Signal Processing Core Tools |
|||

geopsy-fk |
FK processing for ambient vibration arrays. | ||

geopsy-spac |
FK processing for ambient vibration arrays. | ||

Utilities |
|||

gpreplace |
Text replacement using regular expression. Support more features than grep or sed, it can handle patterns over several lines. | ||

Waran |
|||

waran |
Real-time analysis of ambient vibration arrays for WARAN aquisition system | ||

warangps |
GPS Positioning for WARAN aquisition system. Replaces build_array for theoretical array response computation. | ||

Wave tool |
|||

gpdc |
Computation of theoretical dispersion curves. | ||

gpdcmisfit |
Recomputation of misfit. Did you generate a collection of models that you want to use as the starting population for slightly different dispersion curve? No problem, correct misfits and import it. | ||

gpdcreport |
Query tool for binary inversion report produced by dinverdc. With option '-pm' this tool is also usefull for all report types produced by dinver (e.g. dinvermatlab, dinverext or any custom inversion plugin). | ||

gpdepths |
Generates standard thicknesses (that follow a gemetrical progrssion) and corresponding 1D parameterizations. | ||

gpec8 |
Output EC8 soil category from a 1D wave model. Classification here is based only on Vs profiles. The official classification includes other parameters not covered by this tool. | ||

gpell |
Computation of theoretical ellipticity curves. | ||

gpgridsearch |
Generates models with a grid search. | ||

gpgroup2phase |
Convert group velocity dispersion curves to phase velocity. Hmm! The solution is not unique. Ok this tool scans for various possibilities. | ||

gplivemodel |
Interactive computation of theoretical dispsersion curves, ellipticity curves,... through a graphical interface which lets you playing with cursors to adjust model parameters. | ||

gpmodel2param |
Transforms a 1D wave model into a ground parameterization that you can import inside Dinver (dinverdc plugin). | ||
