Inversion |
|||

dinver |
0.5.6 | 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 |
1.4.1 | 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 |
0.2.1 | Plugin to run the forward computation in an external command. | |

swim |
0.1.0 | A graphical environment for the inversion of dispersion curves. Compared to dinver, the parameterization is fully automatic, scanning across all possible numbers of layers (2 to N). Just input a dispersion curve, you will get a collection of good models without making any difficult choice about the parameterization. Though this tool might look as a black box and much easier to use, a good knowledge of the inversion process is ABSOLUTELY required (under development). | |

Plotting |
|||

fastmap |
0.1.1 | Quick drawing of precise maps | |

figue |
1.5.3 | 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 |
0.2.1 | Plugin needed to export graphic signal from Geopsy to Figue. | |

gpcoord |
0.3.1 | Coordinate X,Y oprations: distance, azimuth, conversion from/to lat/long,... | |

gpcurve |
0.1.0 | 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 |
0.1.2 | 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 |
0.1.4 | Constucts interactive 2D histograms from any data set (couples X, Y). | |

gpsort |
0.2.2 | 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 |
0.1.0 | Converts time formats. | |

Signal Processing |
|||

geopsydamping |
1.6.0 | 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 |
2.6.6 | 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 |
0.3.0 | 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). | |
