| 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. | |
| dinvermatlab | 0.1.1 | Plugin to run the forward computation in Matlab. | |
| 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 | |||
